According to the documentation mech_type for gss_init_sec_context() may be passed as GSS_C_NO_OID in which case a default mech should be used. This case was not handled and leads to core dumps when using nss_ldap. Now use the first mech in this case. When there is no mechanism available return an error (this part is taken from the PR).
