I have two problems. More people describe this, but I didnt find answer.

When I use LDAP (AD) with SSL and displaying Users/Groups, sharing group in Admin Console or users login to client, everything is really slow (minutes). When I disable SSL, everything is almost  without delay.

When I use LDAP without SSL and test settings I receive error message:

[LDAP: error code 8 - 00002028: LdapErr: DSID-0C09018A, comment: The server requires binds to turn on integrity checking if SSL\TLS are not already active on the connection, data 0, vece

I had to disable LDAP signing on my DC to make it work.

Is there any way to use SSL with same speed or use LDAP signing?
