Hello all, since moving our Jenkins to use ECS instead of EC2 we are unable to connect to LDAP. The security groups are set ok etc but just keep getting:

javax.naming.AuthenticationException: [LDAP: error code 49 - 80090308: LdapErr: DSID-0C090447, comment: AcceptSecurityContext error, data 52e, v3839]

the only change is that its moved to ecs - anyone else had issues around this?
