I trying to use the "ldap_serach_s" function and my filter works great if put NULL in for the "attrs" parameter.  Here is example filter [(&(member=cn=Bob,ou=colo,dc=bigco,dc=com,dc=local)(objectCategory=Group))] To limit the information coming back from the server I only want the values of the "sAMAccountName" attribute.  Every time I try populating the "attrs" parameter I get an error.   I was wondering if I could be pointed to an example or 2 that uses the parameter.  ThanksDon
