The short answer is, no it does not get updated.
 In-fact, up until windows 2003 it was only updated on the domain
controller which serviced the authentication request and even on 2003 it
doesn't replicate quickly enough to allow you to query just one DC to
obtain an definitive answer without checking and comparing the values
listed on the other DC in the domain

I'm sorry for the people who let you "pull off" data from their AD. If
you
don't know how or when lastlogon is touched, you have no business doing
what
you are doing.

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?
