Allow XMLRPC sync to bypass default auth server in favor of local database
Some organizations with multiple firewall admins are using an external auth server as the system default for authentication. If the XMLRPC sync user is a user on the Local Database, then sync will query the LDAP server first which results in a logon failure. This increases sync time because the LDAP query must time out before it fails over to the Local Database, and generates a logon failure on the remote LDAP server which can trigger automated alerting. If there were an option to select an authentication server for XMLRPC sync similar to other services which have that as a selectable option, this would improve performance and logon failure noise for these kinds of environments.
