SSSD doesn't convert a UID to a name but getent passwd shows all users correctly on RHEL5

Issue

From the customer:

# id e23928d                                                
uid=7268 gid=8113(e23928d) groups=4294967295,102(abc),7268(e23928),7391(xyz),8113(e23928d)
# getent passwd e23928d
e23928d:*:7268:8113:userk:/home/e23928d:/bin/bash
# ls -lad /home/e23928d/
drwxr-xr-x 7 7268 e23928d 4096 Dec 11  2013 /home/e23928d/

Note the groups=4294967295.
