In the gssapi, the call gss_export_name() gets the plain ascii name out of the internal format. You'll notice that the client_principal that was printing out bogusly is a copy of the result of a gss_export_name() on cl_cname. (So, assuming your principal names are printable ascii, as this example appears to be, the result of a successful gss_export_name() will be printable.) Btw, I'm hoping that the second patch "fix race..." will fix this problem, since I doubt that the Kerberos/gssapi libraries are returning trash for the client principal name via gss_accept_sec_context(). --=20 You are receiving this mail because: You are the assignee for the bug.=
