+"""Blackbox test verifying bug 13653
+
+https://bugzilla.samba.org/show_bug.cgi?id=13653
+
+
+When creating a new user and specifying the local filepath of the sam.ldb DB,
+it's possible to create an account that you can't actually login with.
+
+This only happens if the DB is using encrypted secrets and you specify "ldb://"
+in the sam.ldb path, e.g. "-H ldb://st/ad_dc/private/sam.ldb".
+The user account will be created, but its secrets will not be encrypted.
+Attempts to login as the user will then be rejected due to invalid credentials.
+
+We think this may also cause replication/joins to break.
+
+You do get a warning about "No encrypted secrets key file" when this happens,
+although the reason behind this message is not obvious. Specifying a "tdb://"
+prefix, or not specifying a prefix, works fine.
+
+Example of the problem below using the ad_dc testenv.
+
+addc$ bin/samba-tool user create tdb-user pass12#
+ -H tdb://st/ad_dc/private/sam.ldb
+User 'tdb-user' created successfully
+
+# HERE: using the "ldb://" prefix generates a warning, but the user is still
+# created successfully.
+
+addc$ bin/samba-tool user create ldb-user pass12#
+ -H ldb://st/ad_dc/private/sam.ldb
+No encrypted secrets key file. Secret attributes will not be encrypted or
+decrypted
+
+User 'ldb-user' created successfully
+
+addc$ bin/samba-tool user create noprefix-user pass12#
+ -H st/ad_dc/private/sam.ldb
+User 'noprefix-user' created successfully
+
+addc$ bin/ldbsearch -H ldap://$SERVER -Utdb-user%pass12# '(cn=tdb-user)' dn
