Kerberos ticket-based authentication fails with error 'Kerberos GSS token is not verified'

In some cases the Kerberos token sent by the NoMachine client is truncated. This is reproducible only with a client for Windows and occurs with connections by NX protocol. Version 8.5 is also affected.

The user gets:
NX> 500 ERROR: Kerberos GSS token is not verified.

The nxserver.log reports:
ssh_gssapi_error: Major:  An unsupported mechanism was requested
ssh_gssapi_error: Minor: unknown mech-code 1859794434 for mech unknown2891370 2891370 18:08:37 392 NXGssapiCheckToken: ERROR! Security context not accepted.
2891370 2891370 18:08:37 392 NXGssapiCheckToken: Error is 65536.
