Unhandled Exception from MMC about adfsmfa HOT 1 CLOSED

Hi,

According to the transmitted trace, your error is related to a denied access on your Active Directory.
Normally, accessing the ADDS form does not generate an exception in the MMC, but displays an icon next to each invalid attribute.
You must remember that with MMC or PowerShell, the access to Active Directory is made with the identity of the opened Windows session on the ADFS server.

When using the ADDS configuration, the identity you use must have read and write permissions on all users attributes.
As stated in the documentation, it is not recommended to write in an Active Directory, this configuration option should be reserved for testing and POC.
You must also verify that the attributes specified in the default configuration are present in your ADDS functional schema version (Schema 2012) or modify these attributes as you wish.

You can specify credentials either in the MMC form, or with PowerShell
Example:

$ x = Get-MFAConfigADDS
$ x.Account = "domain\account"
$ x.Password = "password"
$ x.DomainAddress = "domain fqdn -> domain.com"
Set-MFAConfigADDS $ x

Finally, you can consider using the SQL configuration

Best Regards
