How to prevent non-admin users of FreeIPA from reading the list of users in the web interface?

by cdknight

When a user signs in to FreeIPA, I do not want them to be able to view the list of users in my LDAP server under the "Active users" link. I still want them to be able to administer self-service, so they can reset their password, add OTP tokens, etc. How would I go about doing this? The users will only be able to access the web interface, so it doesn't matter whether they can access it from other sources.

"Credential cache is empty" error preventing certmonger from renewing a host's certificate

by Sam Morris

I've got an IPA client on which certmonger is unable to renew a certificate. Here are the log messages from certmonger... 2023-06-20 08:24:49 [622035] Certificate submission attempt complete. 2023-06-20 08:24:49 [622035] Child status = 2. 2023-06-20 08:24:49 [622035] Child output: "Server at https://ipa5.ipa.example.com/ipa/json denied our request, giving up: 2100 (Insufficient access: SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure.

In the subsequent output of 'getcert list -i 20220519165212' I saw the same error message displayed but with the name of a different IPA server. So I don't think this is a problem with a particular IPA server. Next I extracted the CSR data from '/var/lib/certmonger/requests/20220519165212' to a file, authenticated as host/myhost.ipa.example.com (with 'kinit -k') and then ran 'ipa cert-request host.req --principal=host/myhost.ipa.example.com', which worked! So perhaps the problem is with certmonger, or with the way in which it interacts with the IPA server that differs from simply running 'ipa cert-request' as I did manually. I also tried to look for logs on the server side, but I didn't find anything very useful. /var/log/httpd/access_log has: 192.168.0.4 - - [20/Jun/2023:13:21:53 +0000] "POST /ipa/json HTTP/1.1" 401 2719 192.168.0.4 - host/myhost.ipa.example.com(a)IPA.EXAMPLE.COM [20/Jun/2023:13:21:53 +0000] "POST /ipa/json HTTP/1.1" 200 526 So it looks like certmonger is having no problem authenticating to ipaapi. httpd is logging: $ journalctl -u httpd -e Jun 20 13:21:56 [121899]: GSSAPI client step 1 Jun 20 13:21:56 [121899]: GSSAPI client step 1 Jun 20 13:21:57 [121899]: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Credential cache is empty) So is looks like ipaapi might be having trouble using Kerberos as a client? I added KRB5_TRACE=/var/lib/httpd/krb5.trace to httpd.service's Environment= and restarted it, then re-ran 'getcert resubmit' on the tracking request. I got these messages: [124285] 1687270136.437160: Initializing FILE:/tmp/krb5cc-httpd with default princ HTTP/ipa5.ipa.example.com(a)IPA.EXAMPLE.COM [124285] 1687270136.437161: Storing HTTP/ipa5.ipa.example.com(a)IPA.EXAMPLE.COM -> Encrypted/Credentials/v1@X-GSSPROXY: in FILE:/tmp/krb5cc-httpd [124285] 1687270136.437163: Retrieving HTTP/ipa5.ipa.example.com(a)IPA.EXAMPLE.COM -> Encrypted/Credentials/v1@X-GSSPROXY: from FILE:/tmp/krb5cc-httpd with result: 0/Success [124285] 1687270136.437165: Initializing FILE:/run/ipa/ccaches/host~myhost.ipa.example.com@IPA.EXAMPLE.COM-h3azdl with default princ host/myhost.ipa.example.com(a)IPA.EXAMPLE.COM [124285] 1687270136.437166: Storing host/myhost.ipa.example.com(a)IPA.EXAMPLE.COM -> Encrypted/Credentials/v1@X-GSSPROXY: in FILE:/run/ipa/ccaches/host~myhost.ipa.example.com@IPA.EXAMPLE.COM-h3azdl No errors there either.

missing attribute "sambaGroupType" when attempting to create a new group - creating groups worked previously

by Tom Spettigue

Hey all - I seem to be getting the following error message whenever I try to create a group via the web interface: ``` IPA Error 4205: ObjectclassViolation missing attribute "sambaGroupType" required by object class "sambaGroupMapping" ``` I'm not sure exactly what's happening, except that I know I've created groups numerous times before, and never gotten this error message. Does anyone have any ideas?

ipa: ERROR: No valid Negotiate header - from/in container replica

by lejeczek

Hi guys. This is my first trial/test of replicas in container - here I added a replica to already existing, bare-metal IPA domain, which otherwise works a okey - so numerous issues are possible. In container, only in this replica, I get: bash-5.1# ipa dnszone-find ipa: ERROR: No valid Negotiate header in server response What that is, might be, a symptom of? Where to go with troubleshooting? All thoughts share are much appreciated. many thanks, L.

Number of concurrent connections are decreased by replication.

by Jaehwan Kim

Hello. I recently encoutered a poblem that nubmer of concurrent connecitons are decreased in FreeIPA servers. [Architecutre - replication topology] My replication topology which is circular (ring-shaped), consists of 13 FreeIPA servers. These 13 servers are grouped as 3 clusters, of which members are 5, 4, 4 respectively. NLBs(network load balancers) to share request from clients for ipa login, kerberos authenticaion, ldap connections, are assinged to each cluster. Therefore 3 NLBs have 5, 4, 4 FreeIPA servers as their nlb backend pool, repectively. This architecture has been worked successfully for 2 years, but recently I encountered a problem that 867 host_add per hours to one cluster results in "# of concurrent connections decrement" for all clusters. Command to get # of concurrent connections is dsconf -D "cn=Directory Manager" ldap://server.example.com monitor server | grep currentconnections: About 2K connections are observed for each servers, by this command. I also found that if servers which replication info isn't transfered to, this symptom doesn't happen, even though those are in the same replication topology ring. Hence, I guess that "# of concurrent connections decrement" symptom is related to replcation. I tried to tune the parameters like dtablesize = 65535, repl-release-timeout = 120, nnsslapd-threadnumber = authomatic thread tuning, db and entry cache auto-sizing (nsslapd-cache-autosize = 80, with failure. I want to ask help to solve this symptom, if posible. Thank you. JHK

DNS resolution failures

by Tania Hagan

Hi Freeipa-users, We are currently running Freeipa version 4.9.11 on Rocky 8.8. We have noticed over the last few months that external name resolution e.g. google.com fails to resolve on multiple Freeipa replicas even though the service named-pkcs11 remains up and running and journalctl or logs aren’t showing up any obvious errors to why this might be happening. We temporarily fix this by restarting the service, but the problem comes back at random times. We currently have 39 DNS Zones Our DNS Global Configuration has a forward policy of forward only, though the individual zones are set to forward first. I’ve read a few articles that say maybe changing the forward policy might fix it, but nothing that mentions how to double check if changing the policy will fix it. Are there any useful troubleshooting checks I could run to either help explain why our service keeps failing at random intervals or confirm any changes would fix the issue without the risk of potential downtime of our DNS service? Many Thanks, Tania

Login failed due to an unknown reason

by Dan West

I am running into a strange issue with a few user accounts where logging into the web interface gives them the error message "Login failed due to an unknown reason”. It also prevents them from SSH’ing into IPA bound systems using passwords. Pubkeys work fine (as long as it is manually added to the local accounts) and any services I have bound to it (Gitlab, Mattermost, Owncloud, etc) seem to work fine. I ’think’ this is kerberos related since the only services that are using it is SSH and probably the IPA web interface. Here is the apache error log for it: [Thu Jan 13 09:15:38.688228 2022] [wsgi:error] [pid 579266:tid 139812542121728] [remote xx.xxx.xx.xxx:52162] ipa: INFO: 401 Unauthorized: Major (851968): Unspecified GSS failure. Minor code may provide more information, Minor (2598844948): TGT has been revoked I ’think’ the message "TGT has been revoked” is due to the 401 error, since the user is not showing as being authorized to login. However, this user is enabled and I have tried a number of things to try to fix it: 1. Disable/Re-enable account 2. Reset passwords 3. Kinit username (seems to get a ticket, but logins still do not work) 4. Run the account migration task (using the web gui) 5. Restart the IPA server and services 6. Re-initialize the IPA server from another master Also, I can confirm that the passwords are correct since a failed password error message shows up differently and other services are using it correctly. Going down the Kerberos path, here is the krb5kdc log file: Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): AS_REQ (7 etypes {aes256-cts-hmac-sha1-96(18), aes256-cts-hmac-sha384-192(20), camellia256-cts-cmac(26), aes128-cts-hmac-sha1-96(17), aes128-cts-hmac-sha256-128(19), camellia128-cts-cmac(25), DEPRECATED:arcfour-hmac(23)}) yy.yy.yy.yy: NEEDED_PREAUTH: WELLKNOWN/ANONYMOUS(a)EXAMPLE.COM for krbtgt/EXAMPLE.COM(a)EXAMPLE.COM, Additional pre-authentication required Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): closing down fd 12 Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): AS_REQ (7 etypes {aes256-cts-hmac-sha1-96(18), aes256-cts-hmac-sha384-192(20), camellia256-cts-cmac(26), aes128-cts-hmac-sha1-96(17), aes128-cts-hmac-sha256-128(19), camellia128-cts-cmac(25), DEPRECATED:arcfour-hmac(23)}) yy.yy.yy.yy: ISSUE: authtime 1642094138, etypes {rep=aes256-cts-hmac-sha1-96(18), tkt=aes256-cts-hmac-sha1-96(18), ses=aes256-cts-hmac-sha1-96(18)}, WELLKNOWN/ANONYMOUS(a)EXAMPLE.COM for krbtgt/EXAMPLE.COM(a)EXAMPLE.COM Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): closing down fd 12 Jan 13 09:15:38 ipa.example.com krb5kdc[579225](info): AS_REQ (7 etypes {aes256-cts-hmac-sha1-96(18), aes256-cts-hmac-sha384-192(20), camellia256-cts-cmac(26), aes128-cts-hmac-sha1-96(17), aes128-cts-hmac-sha256-128(19), camellia128-cts-cmac(25), DEPRECATED:arcfour-hmac(23)}) yy.yy.yy.yy: NEEDED_PREAUTH: testuser(a)EXAMPLE.COM for krbtgt/EXAMPLE.COM(a)EXAMPLE.COM, Additional pre-authentication required Jan 13 09:15:38 ipa.example.com krb5kdc[579225](info): closing down fd 12 Jan 13 09:15:38 ipa.example.com krb5kdc[579225](info): AS_REQ (7 etypes {aes256-cts-hmac-sha1-96(18), aes256-cts-hmac-sha384-192(20), camellia256-cts-cmac(26), aes128-cts-hmac-sha1-96(17), aes128-cts-hmac-sha256-128(19), camellia128-cts-cmac(25), DEPRECATED:arcfour-hmac(23)}) yy.yy.yy.yy: ISSUE: authtime 1642094138, etypes {rep=aes256-cts-hmac-sha1-96(18), tkt=aes256-cts-hmac-sha1-96(18), ses=aes256-cts-hmac-sha1-96(18)}, testuser(a)EXAMPLE.COM for krbtgt/EXAMPLE.COM(a)EXAMPLE.COM Jan 13 09:15:38 ipa.example.com krb5kdc[579225](info): closing down fd 12 Jan 13 09:15:38 ipa.example.com krb5kdc[579226](Error): PAC issue: PAC record claims domain SID different to local domain SID or any trusted domain SID: local [S-1-5-21-997841278-3584560916-1456654135], PAC [S-1-5-21-2108153867-2082035330-3701898995] Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): TGS_REQ : handle_authdata (-1765328364) Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): TGS_REQ (7 etypes {aes256-cts-hmac-sha1-96(18), aes256-cts-hmac-sha384-192(20), camellia256-cts-cmac(26), aes128-cts-hmac-sha1-96(17), aes128-cts-hmac-sha256-128(19), camellia128-cts-cmac(25), DEPRECATED:arcfour-hmac(23)}) yy.yy.yy.yy: HANDLE_AUTHDATA: authtime 1642094138, etypes {rep=UNSUPPORTED:(0)} testuser(a)EXAMPLE.COM for HTTP/ipa.example.com(a)EXAMPLE.COM, TGT has been revoked Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): closing down fd 12 Jan 13 09:15:38 ipa.example.com krb5kdc[579226](Error): PAC issue: PAC record claims domain SID different to local domain SID or any trusted domain SID: local [S-1-5-21-997841278-3584560916-1456654135], PAC [S-1-5-21-2108153867-2082035330-3701898995] Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): TGS_REQ : handle_authdata (-1765328364) Jan 13 09:15:38 ipa.example.com krb5kdc[579226](info): TGS_REQ (7 etypes {aes256-cts-hmac-sha1-96(18), aes256-cts-hmac-sha384-192(20), camellia256-cts-cmac(26), aes128-cts-hmac-sha1-96(17), aes128-cts-hmac-sha256-128(19), camellia128-cts-cmac(25), DEPRECATED:arcfour-hmac(23)}) yy.yy.yy.yy: HANDLE_AUTHDATA: authtime 1642094138, etypes {rep=UNSUPPORTED:(0)} testuser(a)EXAMPLE.COM for HTTP/ipa.example.com(a)EXAMPLE.COM, TGT has been revoked I only see two errors that might be related: "PAC record claims domain SID different to local domain SID or any trusted domain SID” "DEPRECATED:arcfour-hmac(23)” However, those might just be red herrings or something else that is unrelated. So far, there are only a small number of accounts that have this problem, but more seem to be popping up on a daily basis. The only fix I have found is the nuclear option, where I completely remove the account and then add it back in with the same UID/GID, group memberships and policies. After that it seems to work fine. However, I would rather not want to do this to all accounts since that would be a logistical nightmare. Are there any suggestions for either troubleshooting or fixing this problem with a lighter approach? Is it possible to reset or regenerate the users kerberos authentication?

problem allowing Windows Active Directory users to access SMB shares on IPA client machine (IPA has trust with AD)

by Thomas Handler

Hi all, I am facing a problem I got stuck upon. We have the following setup: +-----------+ | | | AD | | | +-----------+ +--------------+ ^ | +----------+ | ums012 | | | | IPA | +--------------+ ^ | +--------------+ | | | | | ums029 | | | | | | smbclient | | +---+----------+ +------+--------+ | | | | | ums025 | | | |<------------------+ | samba | +---------------+ IPA has a trust established with AD which is working fine. Active Directory users can logon on Linux machines which are connected to IPA, `id some-ad-user` properly shows the AD groups. ums012 and ums025 are running RHEL 9.3, ums029 is running RHEL 8.9. ums029 is used as a test client via smbclient. ums025 was setup following the instructions in https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/... Setup worked fine, all steps went ok. But when i switch over to ums029 and try to verify with an ad user I get kinit <ad user> smbclient -L ums025.idm.example.com -U <ad user> --use-kerberos=required Password for [<ad user>@EXAMPLE.COM]: gensec_spnego_client_negTokenInit_step: gse_krb5: creating NEG_TOKEN_INIT for cifs/ums025.idm.example.com failed (next[(null)]): NT_STATUS_INVALID_PARAMETER session setup failed: NT_STATUS_INVALID_PARAMETER whereas this is working fine when running the verification as IPA user. I tried finding hints in the logs but was unsuccessful, thus I’m writing to the list. Best regards, Thomas
