Too many redirects after corect SAML login

[yvangodard]

I try to use your plugin with LS Version 3.19.3+191023.
I installed simplesamlPHP as SP inside LS (https://survey.occitanie-en-scene.fr/simplesaml). This SP works well and correctly connects with our IDP. With a direct connect on simplsaml SP page I obtain all my attributes.
After that I installed and activated your login, after changing the path of my SP with the correct path.
SAML connection with our IDP seems to work, and user is created on Limesurvey table.
But it's impossible to access to the back office, with a problem like "too many redirects".
Any idea to solve this issue ?
And many thanks for your work !
