"wbinfo -u" returns error on a multi trusted domain samba setup.

Issue

• A large Active Directory environment with numerous domains and 100k+ users and groups. The output of the following two commands returns "Error looking up domain users"

# wbinfo -u
# wbinfo -g

• After a restart of winbind the we were able to perform "wbinfo -g" but "wbinfo -u" still failed pointing to insufficient resources.
