Here you can see the DS connection from AIX:
[24/Mar/2015:12:53:19 +0100] conn=96 fd=110 slot=110 connection from 192.168.140.107 to 192.168.140.133
[24/Mar/2015:12:53:20 +0100] conn=96 op=0 BIND dn="uid=bprins at example.corp,cn=users,cn=compat,dc=unix,dc=example,dc=corp" method=128 version=3
[24/Mar/2015:12:53:43 +0100] conn=96 op=0 RESULT err=0 tag=97 nentries=0 etime=24 dn="uid=bprins at example.corp,cn=users,cn=compat,dc=unix,dc=example,dc=corp"
[24/Mar/2015:12:53:43 +0100] conn=96 op=-1 fd=110 closed - B1

As you can see it also takes quite some time to process the login. Could that be a problem?

The SSSD log files are a bit large with debug_level set to 10 and it will take me some time to strip all customer data from it. Any log events in particular you would like to see?
