When searching for the policy groups for an email address via the Control Center Administration -> Users -> Find User page, some policy groups which are based on LDAP organizational units (OU) are not displayed.
LDAP policy groups which are based on an OU with a space in the name are not searched by the Find User feature.
For example, a policy group based on the following organizational unit would not be returned by the Find User feature even if the OU contained a user object with a matching email address:
"OU=Test Orginizational Unit, DC=domain, DC=com"
This is a known issue when using organizational units (objectclass=organizationalUnit) as the base for a policy group rather than an LDAP group (objectclass=group). This issue does not affect policy groups based on LDAP groups, only those based on LDAP organizational units.
