+Subject: [PATCH] Properly renew expired credentials
+
+When a caller imports expired credentials, we aim to actually renew them
+if we can. However due to incorrect checks and not clearing of the
+ret_maj variable after checks we end up returning an error instead.
+
+Also fix mechglue to also save and properly report the first call errors
+when both remote and local fail.
+
+Resolves: #170
