+Subject: [PATCH 1/2] 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.
