I need to implement Microsoft’s LDAP server signing protocol to be able to connect to AD servers that require it but can’t find this protocol description. Is there a protocol description published somewhere?

If it is done from LDAP it is implemented from a SASL mechanism implementation and utilizes GSS-SPNEGO/GSSAPI.
Perhaps the first problem is to determine “What is Signing?”
Which AFIK, Signing implies:
Clients that are signed SASL (Negotiate, Kerberos, NTLM, or Digest) or LDAP binds over a SSL/TLS connection.
So no simple binds or un-signed (ie un-encrypted) SASL mechanisms.
The Negotiate, Kerberos, NTLM, or Digest are implemented from GSSAPI/SPNEGO.
