At this time, the department LDAP server ldap.eecs.berkeley.edu (aka ldap.cs.berkeley.edu) accepts implicit SSLv3 and TLS 1.0, 1.1 and 1.2 connections on port 636, and allow STARTTLS negotiation for the same protocols on port 389.

Beginning Tuesday, February 19th 2019 at 8am, our LDAP servers will no longer accept SSLv3 or TLSv1.0 connections. All clients must use TLS v1.1 or v1.2.

Please send any questions or problem reports to help@eecs.berkeley.edu.
