Find local site for user

[Kenny]

Hello,

I'm making a webapp that allows users to make ldap changes. I would
like these changes to be made on their local site so they don't have
to wait for replication to occur. I know I can make a lookup on
_ldap._tcp.dc._msdcs.domain to find all the servers for their domain,
but I'm not sure how to find what site the user would be in.

Different webpages say that this is usually done through an 'AD ping'
or ldap-over-udp ping. Although I don't know how to do this it appears
it would only return the site for the webserver (the connecting IP).

Can anyone tell me how to find the site for the IP of a user connected
to the webapp? I'm doing this in Java, so any JNDI solutions?

Thanks in advance,

Kenny

From a command line you could run this, I'm not a developer so don't know if
this would help you or not:
nltest /server:192.168.0.1 /dsgetsite

This can only be done when run from the machine the user is logged on to.
The reasoning here is that users don't have sites - they can move around.
Machines are in sites, based on what subnets they
are in.

Actually I may have worded that wrong. I don't need the actual site of
the user, just the site for the machine they are connecting from.

It appears I may have to do some type of LDAP query for the subnets
and figure out which one the machine belongs to. Unless you can think
on an easier way.

Thanks,

Kenny

Kenny-

That will definetely work. I actually have a better solution.

Check out the DsGetSiteName API on MSDN. You pass the computer name to it,
and it returns the sitename.
