When I went through this exercise, I learned that PHP alone was not
going to work well, especially if you ever need to use password
synchronization with another password system (I.E. AD sync). The PHP way
of changing LDAP password essentially involves encrypting and encoding
the password within your PHP application and writing that encrypted and
encoded password directly to the user's password attribute. This
prevents password synchronization to external systems. Ideally you want
to use the ldapv3 ldappasswd mechanism for changing your password within
the directory. That way the directory can read and propagate password
changes correctly. Since PHP did not contain a ldappasswd module, I
ended up writing a PHP front-end which passes the authentication request
to separate Perl script to actually change the password. There is a
similar sourceforge project called locksmith, but it also does the
password changes the wrong way (and encodes shorter passwords
improperly, if I remember correctly.)

I'm trying to come up with a way to do that for them.

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

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!
