KB44218: When defining an LDAP filter using a group name with special characters, the group name is not correctly read and it returns an "Incorrect login/password" error message in the DSSErrors.log in MicroStrategy 9.x

SYMPTOM:
 
When defining an LDAP filter using a group name with special characters like parenthesis (for example "GroupName(Strategy)"), the group name is not correctly read and it returns an "Incorrect login/password" error message in the DSSErrors.log. 
 
CAUSE: 
 
This is caused by the way the LDAP queries are built. By default parenthesis are used as part of the "AND" clause. Special characters can be used as different wildcard types. For example:
 

(&(objectCategory=person)(objectClass=user))   ,     (telephoneNumber=(*)*-*)

 
ACTION:
 
An enhancement request has been logged to provide the ability to use special characters in the LDAP filter. Contact Strategy Technical Support for an update on this request.
 
WORKAROUND: 
 
In order to use special characters in the group names, they must be escaped by the use of a "/". For example:
 

memberOf=CN=GroupName \(Strategy\)
