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

[Luiz Fernando Vianna da Silva]

"Why don't you just use the /bin/sh as default shell in IPA  ? In aix /bin/sh is the same as /bin/ksh and in linux it is a symlink to /bin/bash ."

Wow, never thought of that, very elegant solution!
Atenciosamente/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))

Why don't you just use the /bin/sh as default shell in IPA  ? In aix /bin/sh is the same as /bin/ksh and in linux it is a symlink to /bin/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.

/etc/security/user default:
SYSTEM = KRB5LDAP or compat

I am using the following settings in in /etc/security/user:
SYSTEM = KRB5LDAP
registry = KRB5LDAP
it works for AIX5,6 and 7 in my setup.

/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
