Question & Answer
Question
A user's attempt to start an FTP session with our z/OS Communications Server FTP server is failing. This 534 failure message appears after the client issues the AUTH GSSAPI command:
534 Server is not willing to accept security mechanism
Answer
The message returned by the FTP server, 534 Server is not willing to accept security mechanism, is issued because the FTP.DATA configuration file that the FTP server is using does not have EXTENSIONS AUTH_GSSAPI coded. The IP Configuration Guide points out that specifying EXTENSIONS AUTH_GSSAPI is one of the steps necessary to configure the FTP server for Kerberos.
