Description Kaushik Banerjee 2012-11-08 15:57:03 UTC
Description of problem:
user id lookup fails with proxy provider

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Add a user and group in ldap as:
Group1 --> puser1

2. Setup sssd.conf for proxy provider as:
id_provider = proxy
debug_level = 0xFFF0
proxy_lib_name = ldap
proxy_pam_target = sssdproxyldap

3. # getent group Group1

# id puser1
id: puser1: No such user

Note: You need to run it in correct order as:
# getent group Group1;id puser1
Actual results:
"id puser1" fails.

Expected results:
"id puser1" should work.
