In src/lib/gssapi/spnego/spnego_mech.c for spnego_gss_acquire_cred it has:
OM_uint32
spnego_gss_acquire_cred_impersonate_name(OM_uint32 *minor_status,
const gss_cred_id_t impersonator_cred_handle,
const gss_name_t desired_name,
OM_uint32 time_req,
gss_OID_set desired_mechs,
gss_cred_usage_t cred_usage,
gss_cred_id_t *output_cred_handle,
gss_OID_set *actual_mechs,
OM_uint32 *time_rec)
...
if (desired_mechs == GSS_C_NO_OID_SET) {
status = gss_inquire_cred(minor_status,
impersonator_cred_handle,
NULL, NULL,
NULL, &amechs);
desired_mechs = amechs;
}
imp_spcred = (spnego_gss_cred_id_t)impersonator_cred_handle;
impersonator_cred_handle is a mechanism cred, i.e. an spnego_cred_id_t, not a gss_cred_id_t, and you cannot call gss_inquire_cred on it. The assignment to imp_spcred needs to be moved up and gss_inquire_cred needs to be called on imp_spcred->mcred in the same manner as the subsequent gss_acquire_cred_impersonate_name.
