samba-tool user setexpiry is broken in 4.7

[Andreas Schneider]

Hi,

The command 'samba-tool user setexpiry' doesn't work!

Reproducer:

make testenv SELFTEST_TESTENV=ad_member

$ bin/samba-tool user setexpiry alice --days=4 --URL=ldap://
localdc.samba.example.com --username=administrator --password=locDCpass1
Expiry for user 'alice' set to 4 days.

$ bin/wbinfo --name-to-sid alice
S-1-5-21-1321629873-2603511802-1948877269-1105 SID_USER (1)

$ bin/rpcclient ncacn_np:localdc -UAdministrator%locDCpass1 -c "queryuser 
1105"
User Name   :   alice
...
Password last set Time   :      Tue, 01 Aug 2017 17:50:08 CEST
Password must change Time:      Tue, 12 Sep 2017 17:50:08 CEST


The must change time is 41 days away and not 4 days as set!


Either the test python/samba/tests/samba_tool/user.py does not work as it 
should, or there is a bug in the rpc server.
