Krb5kdc issues tickets on correct passwords, and errors out on incorrect ones.
syslog didn’t reveal any clear hints except “failed password for <user>” from SSH Is there any way for AIX native auth to be more verbose?

GSSAPI authentication is not keeping it simple, since we want passwords to work before trying TGS based logins over GSSAPI. The keytab works sinds lsuser is still able to get user data. (Documentation specifies that enabling krb5 in ldap.cfg makes the bind user and password moot, secldapclntd uses krb5 to identify itself to IPA) Also we are able to kinit host/aixlpar.example....@example.org<mailto:host/aixlpar.example....@example.org> -kt /etc/krb5/krb5.keytab If your kerberos client works (and it looks like it works as long as you can properly kinit) the only option you have is to check the /var/log/krb5kdc.log on the IPA and /var/log/messages or whatever you have configured in syslog for auth. on the AIX client. We van try using su from an unprivileged user, but su has some different issues altogether, it doesn’t like @ in usernames which we need at the next stage (integrating AD Trust) From: Iulian Roman [mailto:iulian.ro...@gmail.com<mailto:iulian.ro...@gmail.com>] Sent: vrijdag 12 mei 2017 15:56 To: Hummelink, Wouter Cc: luiz.via...@tivit.com.br<mailto:luiz.via...@tivit.com.br>; freeipa-users@redhat.com<mailto:freeipa-users@redhat.com> Subject: Re: [Freeipa-users] IPA Compat + ID Views + AIX 7.1 On Fri, May 12, 2017 at 3:31 PM, <wouter.hummel...@kpn.com<mailto:wouter.hummel...@kpn.com>> wrote: The shell is shown correctly as ksh in lsuser, so that doesnt appear to be an issue for the ID view. My advice would be to start simple ,prove that your authentication works and you can develop a more elaborated setup afterwards. If you combine them all together it will be a trial and error which eventually will work at some point. Do you have the correct keytabs in /etc/krb5/krb5.keytab ? can you run kinit (with password and with the keytab) from aix and get a ticket from Kerberos ? can you su to an IPA account ? do you have GSSAPIAuthentication enabled in sshd_config ? From what you've described i would suspect that your keytab is not correct , but that should be confirmed only by answering the questions above.

It may seem silly, but try installing bash on one AIX server and test authenticating against that one. Its a single rpm with no dependencies. For me it did the trick and I ended up doing that on all my AIX servers. Let me know how it goes or if you have any issues.

All the moving parts seem to be working on their own, however logging in doesn’t work with SSH on AIX reporting Failed password for user <xxx> We’re using ID views to overwrite the user shell and home dirs. (Since AIX will refuse a login with a nonexisting shell (like bash)) AIXs lsuser command is able to find all of the users it’s supposed to and su to IPA users works. Also when a user tries to log in I can see a successful Kerberos conversation to our IPA server. Tips for troubleshooting would be much appreciated, increasing SSH log level did not produce any meaningful logging. =============== Configuration Excerpt ================================================================ /etc/security/ldap/ldap.cfg: ldapservers:ipaserver.example.org<http://ipaserver.example.org> binddn:uid=srvc-aixservice,cn=users,cn=accounts,dc=example,dc=org bindpwd:{DESv2}<redacted> authtype:ldap_auth useSSL:TLS ldapsslkeyf:/etc/security/ldap/example.kdb ldapsslkeypwd:{DESv2}4688216124E33174C03FBBB420 88FA8 932F219867AA7C2C552A12BEEC0CC67 useKRB5:yes krbprincipal:host/aixlpar.example.org<http://aixlpar.example.org> krbkeypath:/etc/krb5/krb5.keytab userattrmappath:/etc/security/ldap/2307user.map groupattrmappath:/etc/security/ldap/2307group.map userbasedn:cn=users,cn=aixtest,cn=views,cn=compat,dc=example,dc=org groupbasedn:cn=groups,cn=aixtest,cn=views,cn=compat,dc=example,dc=org netgroupbasedn:cn=ng,cn=compat,dc=example,dc=org automountbasedn:cn=default,cn=automount,dc=example,dc=org etherbasedn:cn=computers,cn=accounts,dc=example,dc=org userclasses:posixaccount,account,shadowaccount groupclasses:posixgroup ldapport:389 searchmode:ALL defaultentrylocation:LDAP /etc/security/user default: SYSTEM = KRB5LDAP or compat /etc/methods.cfg LDAP: program = /usr/lib/security/LDAP program_64 =/usr/lib/security/LDAP64 NIS: program = /usr/lib/security/NIS program_64 = /usr/lib/security/NIS_64 DCE: program = /usr/lib/security/DCE KRB5: program = /usr/lib/security/KRB5 program_64 = /usr/lib/security/KRB5_64 options = authonly,is_kadmind_compat=no,tgt_verify=yes,kadmind=no,keep_creds=yes,allow_expired_pwd=no KRB5LDAP: options = auth=KRB5,db=LDAP Met vriendelijke groet, Wouter Hummelink Technical Consultant - Enterprise Webhosting / Tooling & Automation T: +31-6-12882447<tel:+31%206%2012882447> E: wouter.hummel...@kpn.com<mailto:wouter.hummel...@kpn.com> -- Manage your subscription for the Freeipa-users mailing list: https://www.redhat.com/mailman/listinfo/freeipa-users Go to http://freeipa.org for more info on the project
