user password timeout (password expiry)

[Bernhard Hornung]

Hello!

We are using Samba 2.2.1a as a PDC and I was looking for the password expiry 
functionality, which I consider quite important for security. 

I learnded, that the current Samba release does not support this feature, but 
I found a patch for CVS head in the ntdom mailing list (posted by 
simon at explodingsheep.org in June)

This patch invents the smb.conf parameter "user password timeout = x".  It 
seems to be exactly what I was looking for. 

But  (when I am right), the latest 2_2 CVS does not include this patch. 

Are there any reasons for this? 
Do I have to expect any problems when I apply the patch to 2.2.1a? 
When does the Samba - team plan to integrate this feature?

I will be glad for any information on this subject!
