Description Stephen Gallagher 2011-05-17 16:45:38 UTC
Description of problem:
Attempting to perform an initgroups() lookup of a user that belongs to no groups causes SSSD to throw an error and return no results for the user.

Version-Release number of selected component (if applicable):
sssd-1.5.1-34.el6


How reproducible:
Every time

Steps to Reproduce:
1. Configure sssd using ipa-client-install to point at a FreeIPA v2 server.
2. Add a new user to the FreeIPA v2 server (e.g. newuser)
3. Remove this user from the ipausers group (to which they are added automatically)
4. Verify with 'ipa user-show newuser' that the user is not a member of any groups
5. On the client running SSSD, as root run 'su - newuser'
  
Actual results:
id: cannot find name for user ID 115200007


Expected results:
No error message
