snappymail: login to admin page broken

[chri2]

Describe the bug

Can't access snappymail admin page.

Context

• Hardware: RockPro64 + 2x sata ssd as software raid1
• YunoHost version: 11.2.5
• I have access to my server: Through SSH | through the webadmin
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: yes
  • If yes, please explain: multiple domains for email, added aliases as described here
• Using, or trying to install package version/branch: SnappyMail 2.29.1~ynh1

To reproduce

On my yunohost:

• install SnappyMail (own subdomain snappymail.do.main, path '/')
• go to the admin url https://smail.do.main/app/?admin
• get password from /var/www/snappymail/app/data/_data_/_default_/admin_password.txt
• try to login using username admin and the password from above mentioned file

Expected behavior

Access to snappymails web admin.

Logs

from /var/log/nginx/smail.do.main-error.log:

2023/10/13 17:07:46 [error] 802501#802501: *1446 FastCGI sent in stderr: "PHP message: PHP Notice:  Invalid plugin class LdapIdentitiesPlugin in /var/www/snappymail/app/snappymail/v/2.29.1/app/libraries/RainLoop/Plugins/Manager.php on line 147" while reading response header from upstream, client: 192.168.2.20, server: smail.do.main, request: "GET /app/?/AdminAppData/0/5370959716450588/ HTTP/2.0", upstream: "fastcgi://unix:/var/run/php/php8.2-fpm-snappymail.sock:", host: "smail.do.main"

Seems unrelated, because when I set enabled_list = "" in /var/www/snappymail/app/data/_data_/_default_/configs/application.ini the error vanishes, but still the login to the admin page is not possible.

• I tried to purge and re-install snappymail
• I tried to set the password in the application.ini (snappymail stops to generate new passwords, but the password doesn't work).
