[389-users] notes=A for filter with undefined attribute

Hi,

Xerox printer's LDAP connectivity's default search filter is
(|(uid=someone)(samaccountname=someone)). samaccountname is not a defined attribute. This
search filter will result notes=A, causing performance issue. 

Is there a way to avoid searching samaccountname=someone, since samaccountname is not a
defined attribute. Thank you!
