Onderwerp: Re: [Freeipa-users] 'Preauthentication failed' with SSSD in 


Can you show relevant parts of /var/log/dirsrv/slapd-EXAMPLE-CORP/access
and sssd logs from IPA master (with debug_level = 10) at least in
[domain], [nss], and [pam] sections.

You need to filter dirsrv logs by connection coming from AIX IP address
and then by conn=<number> where number is the same number as the one
with IP address line.

When authenticating, AIX would talk to IPA LDAP server to compat tree
and slapi-nis plugin which serves compat tree would do PAM
authentication as service system-auth where SSSD on IPA master will do
the actual authentication work.

Here you can see the DS connection from AIX:
[24/Mar/2015:12:53:19 +0100] conn=96 fd=110 slot=110 connection from to
[24/Mar/2015:12:53:20 +0100] conn=96 op=0 BIND 
method=128 version=3
[24/Mar/2015:12:53:43 +0100] conn=96 op=0 RESULT err=0 tag=97 nentries=0 etime=24 
[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?
Does the user that you use (bpr...@example.corp) is a member of many large groups?

Thank you,
