Description of problem:
user id lookup fails for case sensitive users using proxy provider. This is
related to bug 874673

Version-Release number of selected component (if applicable):
sssd-1.9.2-41.el6

How reproducible:
Always

Steps to Reproduce:
1. User and group in ldap as follows:
dn: uid=User_CS1,ou=Users,dc=example,dc=com
objectClass: posixAccount
objectClass: account
cn: User_CS1
homeDirectory: /home/User_CS1
userPassword:: U2VjcmV0MTIz
uid: User_CS1_Alias
uid: User_CS1
uidNumber: 304560
gidNumber: 304560

dn: cn=User_CS1_grp1,ou=Groups,dc=example,dc=com
objectClass: posixGroup
memberUid: User_CS1
cn: User_CS1_grp1_Alias
cn: User_CS1_grp1
gidNumber: 304560

2. sssd.conf domain section has:

[domain/PROXY]
id_provider = proxy
debug_level = 0xFFF0
proxy_lib_name = ldap
proxy_pam_target = sssdproxyldap

3. # getent group User_CS1_grp1;id User_CS1
User_CS1_grp1_Alias:*:304560:User_CS1
id: User_CS1: No such user                   <=== id lookup fails after getent

Works fine after clearing cache if I execute the above 2 commands in reverse
order:
# id User_CS1;getent group User_CS1_grp1
uid=304560(User_CS1_Alias) gid=304560(User_CS1_grp1_Alias)
groups=304560(User_CS1_grp1_Alias)
User_CS1_grp1_Alias:*:304560:User_CS1


Actual results:
id lookup fails for the case sensitive user if group is looked up before.

Expected results:
id lookup should work for case sensitive users.
