Above there are two lookups:

- successful lookup for user bpri...@example.com
- unsuccessful lookup for user bprins

What is causing to perform a lookup without @example.com? Compat tree
presents AD users fully qualified, it is the only way it knows to
trigger lookup via SSSD on IPA master for these users (because non-fully
qualified users are in IPA LDAP tree already and copied to compat tree
automatically).
This seems to be (standard?) behaviour of the AIX LDAP client. Did some
more tests with different accounts and always see the two lookups. I
doubt if I can influence that..
No, this is not standard -- I haven't seen such behavior when testing
FreeIPA with AIX last autumn.

OK, with the idsldap client software and an AD trust configured? This is on 
AIX7.1. I'm spinning up an AIX5.3 machine now for another test. Might try 
AIX6.1 as well. What works is creating the user object in freeIPA so the lookup 
succeeds. After that I can authenticate succesfully against AD. Not the 
solution I'm looking for though.
Did some tests with AIX5.3 and then I don’t run into any issues. There is no 
lookup to be seen after entering my username on AIX5.3 (as there was on 
AIX7.1), only the authentication request which succeeds. Will test AIX6.1 later 
on..

AIX6.1 also worked without any problems. In the end my methods.cfg was causing 
the problems on AIX7.1. After deleting these lines authentication worked:

KRB5:
      program = /usr/lib/security/KRB5
      program_64 = /usr/lib/security/KRB5_64
      options = authonly,kadmind=no

KRB5LDAP:
      options = auth=KRB5,db=LDAP

So my methods.cfg now looks like this:

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

I was not expecting this since I was not using KRB5 or KRB5LDAP in 
/etc/security/user. Well, I’m glad I got this sorted out now :)
Great. Could you please write your configurations up somewhere so that
we can have an article on freeipa.org detailing the configs for future
users?
