Hi,
DISCLAIMER: I have zero knowledge of SAML!
me too I think after trying more than a week to get SOGo working with Keycloak...
Having said that, there are two cases where people successfully used it, although not sure if they also used Keycloak. 1. https://www.mail-archive.com/users@sogo.nu/msg29860.html 2. https://marc.info/?l=sogo-users&m=147697076318929&w=2
I already found both post (and many more). But I can't find a post that is written this year and Keycloak changed a lot in the last years...
