Our login setup in our organization involves a campus-wide server variable, which requires redirection to an external website to clear.
Within my custom auth class, I have:
function logOff(){
header("Location:
https://xxx.xxx.xxx/logout/index.cgi");
}
This, however, never allows me to go back to the wiki after logout: I'm always directed to that page.
I had to comment out line 175 in /inc/auth.php within auth_login: the "just to be sure" auth_logoff();
