Cause: LDAP clients wanting to query the root DSE to get some basic information about the directory server without having to use TLS/SSL.
Consequence: If the directory server were configured to require TLS/SSL connections, clients were prohibited from querying the root DSE without using SSL/TLS.
Change: Introduced a on/off type config attribute to cn=config:
by default, the value is off.
when it is off, the server's behavior remains intact.
when it is on, the server allows to access rootdse even if
the ssf value is less than nsslapd-minssf value.
Result: LDAP clients can read the root DSE without using TLS/SSL even if the rest of the server requires TLS/SSL.
