[389-users] Determine when a password is about to expire

[harry.devine at faa.gov]

I can get the passwordexpirationtime value, but I'm unsure what you mean 
by "set the password expiration to occur immediately".  I'm coming from 
the Windows world, so I'm used to the "User must change password at next 
logon" checkbox.  I don't see that anywhere on the GUI, so I'm unclear how 
you set that.

Also, how do I manipulate the dates?  I get something similar to 
20110122161029Z (for example) for passwordexpirationtime.  How do I 
convert that to a proper date format?  Also, I just changed my account's 
password while testing, and I see that passwordexpirationtime got reset to 
19700101000000Z.  What does the 1970xxx value represent?

Thanks,
Harry

Most LDAP servers use a different schema than the Microsoft version and 
work from the opposite direction. Try querying "passwordexpirationtime". 
You can do a search for the specific password schema with the following 
info: 2.16.840.1.113730.3.2.12  passwordObject

I think it is more common to:
1. administratively set the password on a user account
2. set the password expiration to occur immediately.
3. set the passwordGraceUserTime for a time period that allows the user to 
log in solely to change their password.

However, you must explicitly program your site to gracefully handle this 
situation (condition where passwordexpirationtime < now < 
passwordGraceUserTime) , since the user's LDAP authentication attempt 
against the directory will fail (with an error indicating the password has 
expired).

I am in the process of creating a web-based mechanism to allow our users 
to change their password on our new 389-ds server.  I would like to 
display the date that their password is due to expire, and while Googling 
around, I see a lot of references to pwdLastSet, but about 95% of the 
articles are referring to Active Directory.  I don't see pwdLastSet 
amongst the attributes in my default 389-ds setup.  Is it there, or do I 
have to add that attribute to every account? 

Also, I currently have my pages set up where, when the user logs in, it 
detects our 'default' password and forces them to change it.  Is there 
some attribute in their account that I can set that I can key off of and 
force them to change their password when they login to my site? 

Thanks for any tips!
