When a trust domain is down you can not login to your own domain until a timeout about 3 minutes. It's doing ads_try_connect(). Currentlly the code is using ldap_open(). Is it possible to use ldap_init() and set a small timeout using ldap_set_option()?
Much better behavior in 3.0.2rc1. Different approach than changing the timeout value though.
sorry for the same, cleaning up the database to prevent unecessary reopens of bugs.
