The first thing that comes to my mind is to use a database to handle session data as defined by: http://us2.php.net/manual/en/function.session-set-save-handler.php. You can then, when attempting to authenticate, pass the session ID back and forth through your applications. There may be similar things for .Net, but I as I am not a .Net web developer, I can't help you out in that area. -Logan > -----Original Message----- > From: Murtaza Chang [mailto:murtaza.chang@xxxxxxxxx] > Sent: Sunday, April 29, 2007 3:13 PM > To: php-general@xxxxxxxxxxxxx > Subject: single signon Solution php and .net > > Hi, me and my fellow developer have built two applications that need to > authenticate users using LDAP, we have successfully accomplished it, > but the > problem is his application is in .net and mine is in php, my php app > needs > to call secure pages of .net and vice versa, now when the user is > logged > onto let say my php app he is logged and his session is created and > when I > redirect him to .net app he again sees a login form because the session > isnt > created in .net app. > I need some single sign on solution I found lots of APIs and libraries > for > java but have no idea what can I use for php and .net, kindly > experience > programmers guide me. > Thankyou > > -- > Murtaza Chang > http://flickr.com/photos/blackstallion/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
