ERR_TOO_MANY_REDIRECTS

[sgrimmettuk]

Hi,
I have added the files in this project to a new webhosting and have modified the config.inc file as per directions but after seeing the 365 sign in message all I get are errors of ERR_TOO_MANY_REDIRECTS

I have tried using both my single tenant ID and the common setting for Azure, I have checked and my user is set against the enterprise application for access.

I have checked all the requirements you listed, I am running PHP 8.0.28 with CURL 7.29.0.

Can you suggest what I should check?

Many thanks! :)

I am also having this problem, it seemed to crop up out of nowhere...

@sgrimmettuk I was able to fix it (for me) by clearing the site cache in the browser, then deleting the session entries in the database.

Hint: the SameSite-element of the sessioncookie is probably set to Strict. When the redirect to Azure AD happens, the PHP-session is automatically destroyed. So, make the sessioncookie SameSite Lax or None (via the .ini, or by adding something like:

ini_set('session.cookie_samesite', 'Lax'); ini_set('session.cookie_secure', true); session_regenerate_id(true);

just before the redirect to Azure AD happens in modAuth.

I had the same issue, until I realized that my db user was unable to insert entries into the table. Having granted the user full access to this particular db, I overlooked the fact that it also requires write access to the table itself. Otherwise, no session will be stored and the redirect to Entra AD will happen constantly.
