[Freeipa-users] IPA Compat + ID Views + AIX 7.1

[wouter.hummelink at kpn.com]

The shell is shown correctly as ksh in lsuser, so that doesnt appear to be an issue for the ID view.

Hello Wouter.

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.
Best Regards

Hi All,

We’re running a POC to integrate IPA and AIX using AIX KRB5LDAP compound module.
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.
