Error - Windows Seamless Login & WSS 3

  Asked By: Reuben    Date: Dec 13    Category: Sharepoint    Views: 1638

I am the project manager for the WSS 3 based intranet we're
implementing at the company I work for. We would like for users to be
able to use Windows Seamless login to access the intranet(use the
credentials they login into their machine with to authenticate in
Sharepoint), but we're getting inconsistent results. When users add
the URL for our intranet into their Local Intranet sites list in IE,
some users can get into the site without entering their password and
others just time out when they try to access the site. Some staff
authenticate have inconsistent results - for example they sucessfully
connect in the morning, but not in the afternoon (from the same
location / connection type). Has anyone experienced this before? Does
anyone have any ideas on how to troubleshoot this?

If you are using IA (integrated authent) with Kerberos, then both the
client and WFE Server must see the KDC, in addition to a maximum of 5
minutes time  difference between client/WFE

If you are using IA with NTLM, be aware that NTLM is connection-based.
So, if a proxy server, some firewalls, etc, are between, the IA could

Sometimes (about 1 in 1000 in my experience) IA just doesn't work  from a
client machine. In that case, deleting and re-adding the user profile on
the client machine  fixes the problem.

For the user that are being prompted or having inconsistent  results, check their
settings of the Local Intranet and make sure it has Login with current
username/password selected

Reference the ones you know are set up correctly and can log in part
of the time  and then not again later. If you fix them you will
prbably take care of 90% of your problems. I had the same problem
and it was my connection  timeout settings. Looks like the response
time is probably timing out and thats why the logon is not
successful. Might have higher usage in the afternoon on the network
and its slowing things down. Try increasing timeout settings. Also,
have you looked in the server logs, or asked a server admin to do so,
to see if they are failing authentication? At least that way you can
see on what side the problem lies.

I wouldn't think they should have to use any password  using windows  based
authentication. You are able to figure out who they are (authentication)
via the NTLM token. This means based  on their AD role you should know them.
I think the time  out issue is something else.
