LDAP Attribute Lookup fails only when an attribute name contains a space. Other LDAP Attribute Lookups succeed.
Data Loss Prevention Enforce 12, 12.5, 14, 14.0.2, 14.5, 14.6
If the attribute name field requires a space character, you should "escape" it with a backslash (\).
For example,
attr.Manager\ Email = DC=ofi:(distinguishedName=$TempMan$):mail
For DLP versions older than 12.0, please see TECH221114
