Subject: RE: Active Directory accounts


Hi

We have recently developed a script to gather detailed user information from our AD in order to identify user accounts not used for a long time and proceed with deletion of such users. 

During our test, at least we have observed that the LastLogon property is changed not only with the interactively logon to a desktop system, but also while mapping a network drive. We have not tested it with third party applications that make use of the AD just as and LDAP for authentication, but it is very likely that this property will also be updated this way.

Regards,

Asunto: [Full-disclosure] Active Directory accounts

Hello,

I have a question regarding some data I pulled off a
customers AD. We recently ran AD scan to identify
several user accoutn violation types using AD
Inspector (www.obtuse.net/software/adinspector).
Basically the search contained filters for users who
dont have password expirations enabled and also users
who havent logged in in the last 90 days (stale
accounts). Anyways, the results were quite suprising
and I'd like to validate them.

My question is this. Is the lastLogon AD account
property updated any time a user authenticates to AD
regardless of the service? Like, if I login to a 3rd
party application which uses LDAP integration with AD
for authentication, will that update the users
lastLogon property in AD?
