Enabling kerberos in WINSCP

Hello,
i have installed openssh and WinSCP on Windows 2016. Kerberos Single Signon is working with other tools. Now I tried to configure WINSCP to use kerberos.
I have disabled "Attempt authentication using Pageant" and enabled "Allow GSSAPI credentical delegation". Then I choose SFTP protocol, FQDN name of the host, port nummer (990) and username.
After save the configuration I have checked the global preferences. My changes are not saved. What is my mistake ?

What "global preferences" are you referring to? There are no global preferences for Kerberos. Do you mean the default session settings?

Thank you, I've found my mistake. The advanced settings SSH - Authentication are correct now for SFTP connection. But I can't set the keberos settings for protocal FTP -TLS/SSL. Why ?

WinSCP does not support Kerberos for FTP (for TLS/SSL in general).
