Remmina 1.4.35-2 does not connect to Windows RDP server

When trying to connect to a Windows server a black screen is shown, and it never connects. Downgrading to 1.4.35-1 works.

It shows this error in the journal log
[16:22:19:729] [1855:00001ef8] [ERROR][com.winpr.sspi.Kerberos] - [kerberos_AcquireCredentialsHandleA]: krb5glue_get_init_creds (Cannot find KDC for realm "CENSORED.ORG" [-1765328230])

It looks like 1.4.35-2 was updated to use FreeRDP 3 , so that's most likely the reason.

The Flatpak version works, but that doesn't seem to use freerdp 3 either https://gitlab.com/Remmina/Remmina/-/bl … .json#L532

There seem to be some issues related to the fact that freerdp3 switched to using kerberos by default to authenticate and that requires a working config. Relevant issues: Remmina, FreeRDP. In the meantime I think a quick fix would be to also build remmina with freerdp2 like the flatpak version.

Looking through the freerdp issue, it seems that there is a build option for freerdp to enable NTLM (old authentication method) fallback in case kerberos fails. Not sure if it's enabled by default or not and also how new that option is, might just need to be updated to have it.
