[Samba] Attempts to Set Max Password Age in Samba Tool Fails




Hello!


I am on Samba 4.10.0, Ubuntu 16.04.2 LTS. I recently reset a password and found that my password expiration had somehow gotten set to 400 days.


I went to one of my DCs and ran the following command:



# samba-tool domain passwordsettings show
Password informations for domain 'DC=samdom,DC=mydomain,DC=com'


Password complexity: on
Store plaintext passwords: off
Password history length: 5
Minimum password length: 14
Minimum password age (days): 0
Maximum password age (days): 400
Account lockout duration (mins): 60
Account lockout threshold (attempts): 30
Reset account lockout after (mins): 60


That needed to change so, I tried to enforce my company's policy:



# samba-tool domain passwordsettings set --max-pwd-age=270
ERROR(<class 'TypeError'>): uncaught exception - unorderable types: NoneType() >= int()
  File "/usr/lib/python3/dist-packages/samba/netcmd/__init__.py", line 184, in _run
    return self.run(*args, **kwargs)
  File "/usr/lib/python3/dist-packages/samba/netcmd/domain.py", line 1513, in run
    if max_pwd_age and max_pwd_age > 0 and min_pwd_age >= max_pwd_age:


I tried several numbers for max-pwd-age, they all sent the same error. I tried setting the min-pwd-age to 0 again, even though it was already 0. That command was successful, but it didn't help at all. Am I doing something wrong? Any advice?


Thanks,

Matthew
