Bug 1326129

Description of problem:

user groups from ldap trusted forest are not retrieved.

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

5.5.3.4.20160407153134_b3e2a83

How reproducible:
always

Configuration:
1. Create the user "ldaptest" and group "engineering" in ldap:"cfme-qe-ldap", and add "ldaptest" user to "engineering" group.
2. Create the user "ldaptest" and group "cfme" in ldap:"cfme-qe-ipa" and add "ldaptest" user to "cfme" group.

Steps to Reproduce:
1. Login as "admin" and navigate to configure->configuration->authentication
2. change the authentication mode to 'ldap'
3. specify the hostname for the "cfme-qe-ipa", as the primary ldap.
4. in the "Role Settings" check "Get User Groups from LDAP", observe that "Trusted Forest Settings" table displayed below. specify "Base DN" and "Bind DN"
5. click on '+' to add "Trusted Forest Settings", specify HostName as "cfme-qe-ldap",enter valid Base DN, Bind DN and 'Bind Password' click add the trusted forest and click "Save"
6. navigate to "access control"-> "groups"->"add new group", check (Look Up LDAP Groups), specify the user "ldaptest", click retrieve. Observe that only the groups(cfme) from Primary ldap (cfme-qe-ipa) are retrieved. no group(engineering) from "cfme-qe-ldap" is reqtrieved.
7. manually add the group "engineering", logout and login as "ldaptest". Observe that login fails for the user "ldaptest"

however, the "engineering" group retrieve works and login for "ldaptest" works if "cfme-qe-ldap" is specified as the primary ldap.

Actual results:
user groups from ldap trusted forest are not retrieved.

Expected results:
CloudForms Management Engine is expected to first collect all of the user’s groups from the primary LDAP directory. Then it is expected to collect any additional groups that the user is a member of from all of the configured forests.
