This query is essential to mock Active Directory service.
I think it will be enough just ignore this filter rule.
Right now, mokapi fails this query:
ldapsearch -x -h localhost -p 389 -b "dc=example,dc=com" "(!(userAccountControl:1.2.840.113556.1.4.803:=2))"
with this:
time="2025-12-25T00:39:10+03:00" level=error msg="ldap error: unsupported filter 9 requested"
time="2025-12-25T00:39:10+03:00" level=error msg="ldap panic: runtime error: invalid memory address or nil pointer dereference"
