[SSSD-users] Unable to get group membership

[Michael Dahlberg]

I'm trying to obtain group membership of accounts that login via SSSD against an AD
environment (id_provider = ldap, auth_provider = krb5).  Authentication completes
successfully and the UID and GID values are correct for the logged in user account:

uid=1113938(username) gid=1000 groups=1000
context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

but where there is
"context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023" there should be
a list of user-managed groups that the user is a member of.  These groups are contained in
an Active Directory environment.

A debug log (debug_level = 6) shows the following segment which repeats on and on:

I can query the AD using ldapsearch and get a group membership list, but I can't seem
to get that data using SSSD.  What sssd.conf option should I be using to successfully
obtain this data?

Thanks,
Mike
