I updated today my Grommunio installation at Leaf 15.
After that I logged into admin account and add a new domain, add a new user, set the DNS settings correct and want to login in WebApp (and smartphone and outlook), but a login is not possible.
In nginx-web-error.log there is this error message:
2022/10/31 12:27:52 [error] 2513#2513: *332 FastCGI sent in stderr: "PHP message: grommunio Web user: marco@marco-welter.de: authentication failure at MAPI" while reading response header from upstream, client: 91.196.146.254, server: _, reques: "POST /web/?logon HTTP/2.0", upstream: "fastcgi://unix:/run/php-fpm/grommunio-web:", host: "gromox.555cloud.de"
The version (grommunio-admin version) is 1.8.2+1 and the OpenLeap version is 15.3.
I could not find anything, can anyone help me?
