Hello We are currently using freeradius 2.1.12 which works fine. I tried to install 3.0, everything went fine except ldap. When I try ldaps on port 636 it fails on startup with: rlm_ldap (ldap): Connecting to SERVERNAME:636 rlm_ldap (ldap): Bind with CN=USERNAME,OU=XXX,DC=XXX,DC=XXX,DC=XXX to SERVER:636 failed: Can't contact LDAP server rlm_ldap (ldap): Opening connection failed (0) rlm_ldap (ldap): Removing connection pool /usr/etc/raddb/mods-enabled/ldap[1]: Instantiation failed for module "ldap" With ldap on port 389 it starts but fails when I connect with: (35) ERROR: Failed performing search: Please set 'chase_referrals=yes' and 'rebind=yes'. See the ldap module configuration for details. (35) ERROR: Server said: 000004DC: LdapErr: DSID-0C0906DD, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1772. I have chase_referrals=yes and rebind=yes in ldap module file and tried to move it around without success. The AD account and settings works in 2.1.12 MvH Mikael Tomt It-Enheten Mora, Orsa, Älvdalen
