OOOps: I note that you're trying to use a sort of relational
filter; LDAP only supports AVA filters, i.e. you can assert
a value of an attribute, not relations among attributes. 

"(!(a1=a2))" is treated as "a1 != 'a2'", that is the right hand side
is treated as a literal string, not an attribute name. 

Again, see RFC 2254
