 * Our LDAP authentication suddenly stopped working. We had it working for years,
   I can’t recall making any LDAP changes lately. Every user, including admins, 
   gets the same error: ERROR: Unknown error in LDAP Authentication. We would like
   to try to point WordPress to use a different LDAP server but we can’t make any
   changes since no one can sign in. Is there any way to make changes manually? 
   What file holds LDAP server info? Thank you.

 * [@jspahic](https://wordpress.org/support/users/jspahic/) have you been able to
   figure this out? I am migrating from Bluehost to WP Engine. The only issue is
   the LDAP plugin not working.
