One login only

[Ja...@generaldynamics.uk.com]

Hi,

 

I'm currently trying to configure Tomcat to only allow a user to log in
once.  If the same user tries to log in when already logged in (from
another machine for example) I want to cancel the login request and
present an explanation to the user.  I'm using the FORM based
authentication and have searched the web for a solution to this problem
to no avail.

 

Any help would be much appreciated,

 

Jamie

Greetings from across the Pond

I thought this was rather an ingenious solution
http://www.simongbrown.com/blog/2004/11/04/1099588633312.html
Create a Principal object
Authenticate Principal object to Tomcat Realm via 'Role'
then use SSOValve to create Principal from supplied RequestHeaders

Does this help?
