[Samba] Problem changing password - Samba 3.0.13

[Richard Smart]

First thank you to the team for the Samba software. I have been using 
this on a number of sites with excellent results and very few 
problems over the years.

I have just upgraded two sites to Samba 3.0.13 from 3.0.11. Both 
sites are small and use smbpasswd as the password db backend. Since 
the upgrade I am unable to change a users password (as root) using 
smbpasswd. 

There are two reported errors  

account_policy_get: tdb_fetch_uint32 failed for field 4 (maximum 
password age (seconds since 1970)), returning 0
account_policy_get: tdb_fetch_uint32 failed for field 5 (minimum 
password age (seconds since 1970)), returning 0

The systems are both RedHat 9.0, Samba was installed using RPMS from 
samba.org 

Converting the smbpasswd file to a tdbsam and then reconfiguring 
Samba to use passdb.tdb makes no difference.

Using pdbedit to import the old smbpasswd and export as a new 
smbpasswd file makes no difference - so I do not think that this is a 
problem of an old format smbpasswd file - although that was my first 
thought.

Reverting to samba 3.0.11 fixes the problem.

Has anyone any suggestions please?

Thank you
