plugin wpCAS gives infinite loop

Hello,

I’ve added the wpCAS plugin in order to do the authentication from my cas server. Configuration looks good because the redirection from login form to CAS server is working.

But after the CAS authentication form has been sent, an infinite loop arrives between wplogin.php and my cas server.

This loop contains :
1) a call to https://myblog/wp-login.php?ticket=ST-5201-FkbVseg5cQKzMJ5Qz11n-casX
2) and then a call to https://myblog/wp-login.php
3) and then https://myCasServer/cas/login?service=http%3A%2F%2Fblog.soat.fr%2Fwp-login.php
4) it returns to 1) until my browser gives up

Do u have any idea how to solve this ?

I’m using CAS 1.0.1, WP 2.9 and wpCAS 1.0.7
(I’ve got the same problem with cas-authentication plugin)
