Hi linux-cifs, products coming with MIT krb5 < 1.7 (like SUSE Linux Enterprise 11 SP 1 or SP 2) suffer from the same issue as described by https://bugzilla.samba.org/show_bug.cgi?id=6918 The declaration of krb5_auth_con_set_req_cksumtype is missing. The attached patch fixes this issue. Cheers, Lars -- Lars Müller [ˈlaː(r)z ˈmʏlɐ] Samba Team + SUSE Labs SUSE Linux, Maxfeldstraße 5, 90409 Nürnberg, Germany
