Subject: [PATCH] auth: Fix handling passdbs with identical driver/args but
different mechanisms/username_filter
The passdb was wrongly deduplicated in this situation, causing wrong
mechanisms or username_filter setting to be used. This would be a rather
unlikely configuration though.
Fixed by moving mechanisms and username_filter from struct passdb_module
to struct auth_passdb, which is where they should have been in the first
place.
