It appears as though this is a bug.  Network Identity Manager takes a very long 
time to return when obtaining new credentials over the VPN.  This is more 
pronounced on slower network connections.  Delays of around 1 minute on a 
wireless connection here on campus in comparison to 2-3 minutes when connecting 
from off campus.

It appears as though there are valid tickets created right away, but the 
authentication dialog box stays open for some time afterwards.  I included 
screen shots below to show that valid tickets are created at 12:47:39, but the 
authentication dialog box doesn't go away until 12:48:23.  About 40 seconds.  
This time is more when on a slower network connection like DSL.

In testing, applications that use Network Identity Manager to get tickets for 
authentication, ex. SAPGui,  seem to wait until this authentication dialog is 
gone before finding the tickets.  This problem was noticed by Steve Landry 
while working on RT ticket #1219033 
(https://help.mit.edu/Ticket/Display.html?id=1219033).

Any idea as to why Network Identity Manager is taking so long to return after 
obtaining tickets when connecting via the VPN?

If you have any questions, please feel free to ask.
