LDAP filter with two different OUs and groups

[norrcomm]

I am trying to setup an LDAP filter for two different LDAP groups

When I configure one LDAP group like this, it works:

memberOf=CN=&group1,OU=temp_staff,DC=internal,DC=company,DC=com

When I configure the LDAP filter with two LDAP groups like this, it fails:
(memberOf=CN=&group1,OU=temp_staff,DC=internal,DC=company,DC=com(memberOf=CN=&group2,OU=permanent_staff,DC=internal,DC=company,DC=com))

Is there a way to make this work as intended?
