Authentication

Dear community,
we are testing OpenID connect and o365-authentication with Azure in our Moodle 3.5.7+ and we have some questions about Azure sync issues:

Cron-Job: Sync User with Azure AD
According to the official Moodle and Microsoft-instructions the cron job will synchronise 1000 accounts per job. In our installation it seems to be that there are only 100 accounts synchronised per cron job. Does anyone also have this issue? How can I increase to 1000 accounts per sync?
(workaround: we increase the cron job interval to serveral times per hour)

User Field Mapping: custom fields
in the plugin settings we only can choose a few AD Fields (Given Name, Surname, Email, City, Country, Department, Language, ...).
Is there any possibility to add more fields, eg. Description or custom fields?

Synchronisation settings between MS Teams and Moodle
A moodle admin can change the sync settings (local_o365: createteams). We changed it to "customize groups", so we can decide which courses will also get a Microsoft Team. Most of our courses will be created automatically via Webservice from our student management system, so we can also integrate the creation of a Microsoft Team in this system. Is there any possibilty how we can change the customize group-settings of each course also via webservice? I didn't find any function ...

thanks, best regards

Anton
