Return GSS_S_NO_CRED from krb5 gss_acquire_cred Earlier versions of the GSS-API spec (RFCs 1508 and 2078) do not list GSS_S_NO_CRED as a valid error code for gss_acquire_cred. As a result, the OpenVision developers of the GSSAPI krb5 mech created GSS_S_CRED_UNAVAIL as an alias for GSS_S_FAILURE and returned it when no valid credentials could be obtained. RFC 2743 lists GSS_S_NO_CRED as the proper return code when matching credentials cannot be accessed. Change the krb5 gss_acquire_cred() implementation to return GSS_S_NO_CRED where it currently returns GSS_S_CRED_UNAVAIL. Also stop using GSS_S_CRED_UNAVAIL in the krb5 gss_store_cred(), but change it to explicitly use GSS_S_FAILURE instead. RFC 5588 specifies GSS_S_NO_CRED as indicating a problem with input_cred_handle, not the receiving store, so GSS_S_NO_CRED would be inappropriate. https://github.com/krb5/krb5/commit/eb8d2ced232e60613b461b4410f6fff3800467ab Author: Greg Hudson Commit: eb8d2ced232e60613b461b4410f6fff3800467ab Branch: master src/lib/gssapi/krb5/acquire_cred.c | 16 ++++++++-------- src/lib/gssapi/krb5/store_cred.c | 4 ++-- src/tests/gssapi/t_add_cred.c | 2 +- 3 files changed, 11 insertions(+), 11 deletions(-)
