The way I understand his requirement (RE: "I want for them to use their
password once and only once.") is this: He wants a tech to go to a
self-service system, get a password for his/her account, be able to use THAT
password to log into ServerA and NOT ServerB. He wants that password to
expire upon first login so that the same username/password combo can not be
re-used. If that user needs to log into another system after the
instantaneous expiration, (s)he has to go and request another password (for
THE SAME ACCOUNT).
 
Unless I've grossly misunderstood you, this sounds too James Bond-ish to me,
and I don't believe  limitlogon can do that.

The logon script could do it directly, but to do so means that the userid has
the ability to modify its own pwdLastSet value and a bright support person
will know to simply unexpire the account if they want. The script would have
to contact some service and ask for the lockdown. This would all be custom
code. Probably a web service or something like that which the script calls
out to and says "Hi I am logged on" which then tells the service to lock down
the account. 
 
I guess you could look into the limit logon tools as well to help with this.
That tool will allow you to specify that you can only be logged on one place
at once though I haven't used it to figure out where the holes are. Others on
this list have played with it though.

Heck you could probably even tie into that code somehow when a logon is
processed it fires something on the server to call out to a DC and lock the
account.

No.  That is not what is happening.

 

I work for a web hosting that has thousands bastion host servers that are on
a domain.  These servers are accessed multiple times based upon need by the
support staff.  So that there is no universal password among all servers (for
obvious reasons) we have this system in place (dynamically assigned passwords
for users).  The problem is that a support technician can log into multiple
machines at once providing that they login before their password expires.
This is what I want to prevent.  I want for them to use their password once
and only once.  I want for their password to expire upon first successful
authentication use.

 

Joe, based off of our statements, would it be possible to have a logon script
communicate to the DC and then update a property of that user to immediately
expire their password?  If so, can you provide some direction?

 

Thanks,

Edwin

If the whole goal is to disallow access to other machines and it has to be
enforced, I would not use a domain ID. I would work with local IDs on the
specific machines, these IDs should not be the same as the IDs on other
machines and shouldn't have passwords in sync. That way if anything breaks
that is supposed to go back and lock down access the folks still don't have
access to other machines. They could have access to log into the local
machine again which may be a pain but if they were just on it, I don't see
that as incredibly bad. You can obviously use the same or a similar mechanism
currently in use to lock down the ID after 2 minutes. Another solution to
lock the ID down quickly on the local machine would be to have a service that
just watches an account and once it shows password not expired, sleep 5
seconds and then change the password and expire it again. Any lockdown done
on a domain ID would not be fully in effect until replication carried that
change to all DCs. It could get messy if DCs in different sites were used.

 

I guess if you wanted to get really fancy (read complex and subject to
failure and issues) with a domain ID you could have a logon script for the
ID, the logon script sends a request to some machine with then locks the ID
down, then the script keeps querying that machine and the machine says STOP
until it has detected that the ID has been locked down on all DCs, then the
script gets a GO message to continue the logon. If the GO doesn't come in x
seconds/minutes, the logon script tells the user there has been a problem and
logs them back off without ever letting them do anything.

Basically, you want them to have a one-time-use password?  Is that correct? 

 

That's interesting.  I haven't seen anything like that, but I imagine that's
something that allows an outside vendor to have remote access to do something
they need to do, but for security reasons you wouldn't want them to have full
access to everything. 

 

I wonder if it would be better to grant them access to the machine they'll
access when they reset the password to prevent them from accessing other
machines? i.e. Reset password & limit the desktop they can access at the same
time. Would that give better control? 

 

Aside from that, can you define the exact requirements a little more?  I
think it might jar somebody's thinking a little more to hear some additional
information about the requirements. 

 

My initial thought, if the above doesn't get you closer to the requirements,
would be to use a logon script or change in the code to do this.  Maybe with
a timer.  I.E. reset the password, set it to expire at x minutes (if that
helps), limit the machine it can logon to, and after x amount of time check
for usage.  If found, reset the password. 

 

I do have to ask if this would allow them to accomplish the function they
need to accomplish however. I wonder if you're not giving them enough time to
do what they need to do. 

 

My rambling thoughts anyway.

Hello Everyone,

 

I have an application that allows different users to reset a special domain
account that allows for RDP sessions to be established on thousands of
machines on a domain.  These usernames have a policy that forces the password
to expire within 2 minutes.  If the password has expired, they must reset the
password from within the application again to gain access to another server. 

 

I am aware of the password expiration policy(ies), but I would like something
different.  What I would like to do is force a user to reset their password
upon first use.  As it stands, I can reset the password and still
authenticate to many other servers as long as I am within the 2 minute
expiration rule. 

 

How can I have force a password to expire upon first use?  Is this possible?

 

Thank you for your replies,

Edwin
