[Samba] Modifying accounts in User Manager disables account!

[Brandon Turner]

I've just posted this as bug 1320:

If an administrator users Microsoft User Manager to modify a user
account, the 
account becomes disabled.  I have noticed that Samba 3.0.3 
adds "sambaKickoffTime: 0" to the LDAP account for the user.  If you
give the 
account a expiration date in the Account Information section of User
Manager 
instead of 'Never' the account is ok.  It seems when trying to make the
account 
never expire, Samba 3.0.3 puts 0 for the sambaKickoffTime attribute
instead of 
2147483647.  Previous versions did not modify/add this attribute.
