No Login to Azur AD Usersource

Hello,

I have successful configures AzureAD as usersurce and I see all users and groups.

But on the client at login window of zapp I didn´t see the azure ad, but all other user sources in the pulldown menue.

In the registy the key domainlogin key is set to 1.

Also the key AlternateAzureDomain(REG_SZ) is set to the display name of  the name in ZCC usersource.

Is this correct?

I also tried domainlogin key is set to 0.
