How to add an exception to an ldap request?

Question

LDAP

Good day to all.
Tell me, there is an AD with a bunch of users, and a configured LDAP, which, as an example, calls to look at these users in the thunderbird address book. Is there a way to filter some of the users? By name or something else so they don't show up in the address book.
Now the request looks like this:

(&(sAMAccountName=*)(|(sAMAccountType=805306368)
(sAMAccountType=268435456)
(sAMAccountType=268435456))(mail=*))

Answer 1

Use sign !
As an example:
!(sAMAccountType=268435456)
