I use OpenLDAP 2.4.19 and I try to build an own gender attribute.
Why not use existing suggestions?
I need a custom syntax for the value, "M" or "W".
With OpenLDAP you don't need an extra syntax. You could use slapo-constraint for restricting attribute values. See the man-page slapo-constraint(5).
How can I create my own custom syntax?
An own LDAP syntax requires coding something which runs inside slapd (e.g. an overlay).
