Hi all,  
I am working on a webapp where a user can login, the login process binds  
with LDAP to see if the user is in LDAP. If its successful, I store the  
params[:login] to a global variable so I can use that in the rest of the  
application.

The problem is:  
When i open up two browser windows and login in with two different  
users, the variable is set to the user information used in the second  
login. So when I switch back to the first browser window and refresh, I  
see the second user information. Hopefully this makes sense, if not  
please let me know. I will rephrase it.

Thanks,  
Dev

That behaviour is to be expected if you are using a global variable…  
What you probably want to be doing is storing it in a session variable  
instead.
