Had major issues with backups a while ago, it was due to the firmware of the NIC in the physical server. We found out by moving our XO vm to another physical host and then error went away, moving it back made it come back.

@gcpeters4 said: Is there a way to specify a primary and secondary Active Directory server when configuring auth-ldap? I've encountered situations where the specified URI (ldap://activedirectory1.domain.x.y) server isn't reachable so I'd like to be able to specify a secondary AD server using something like this: ldap://activedirectory1.domain.x.y, ldap://activedirectory2.domain.x.y Basically multiple AD servers; separated by a comma. Unlike the other forum post regarding Multiple AD Sources, both of these control the same domain. Thanks. Another option is to setup AD clustering (clusters) with both controllers part of the same cluster. Alternatively setup an AD Failover which has a single FQDN endpoint but two members. Either or both of these likely to result in a single FQDN that can be fed into the plugin.
