I have "SOGoMailAuxiliaryUserAccountsEnabled = YES;"

I can see the Link to add another IMAP Mail Account from the SOGo Webmail

I can add an account and when I click on "save" a message appears that
everything is fine and successfull.

But coming back to the Mailfolder the additional Mail account isn't there.....

I don't see any errors in the sogo logs - all debug options enabled.

Using apache or ngnix doesn't resolve the problem.

But Using the sogo-tool works!
sogo-tool user-preferences set defaults user@dom.de AuxiliaryMailAccounts '{"AuxiliaryMailAccounts": [{"password": "**", "userName": "imapaccount", "identities": [{"email": "mail@addr.de", "signature": "test signature", "fullName": "Vor Nachname"}], "encryption": "ssl", "serverName": "themailserver.de", "name": "NameOfAccount"}]}'"

But using the sogo-tool I can add only one additional imap account.
When adding a second one, the first will vanish an the new (second)
appears instead of the first.
