Double Twice Credentials to login to farm

Hi all,

After the Collection Security settings on Windows Servers 2016 RDS, has been configured to -

Security Layer: RDP Security Layer,

Encryption Level: Client Compatible,

no check on "allow connections only from computer running..."

that changed was made in order to enable users to change their password when expired.

now users have to enter their password twice in order to login,

the GPO is configured with 'Always prompt for password upon connection‘ to disabled.

any ideas ?

thanks a lot!
