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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I'm using PHP since I'm trying to make a web-based mechanism for our users to change their passwords.  Many of them aren't exactly tech-savvy, and are used to the old Windows way of logging into our Windows machine, and being told that they must change their password.  I'm trying to come up with a way to do that for them.

Thanks,
Harry

Harry,

This is the pattern I use to parse the date in java: "yyyyMMddHHmmss'Z'".  You can probably deduce what the values represent by looking at the pattern.  Also the times are stored in UTC so you'll probably want to convert that to the local timezone if you're going to display the date/time to the user.

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?

What programming language are you using?
http://en.wikipedia.org/wiki/ISO_8601 - the format is used with no separators (e.g. 20110122 instead of 2011-01-22) and no "T" between the date and the time.
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?
That is a special value meaning the password needs to be changed.

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!
