I've been having also sorts of fun trying to get kerberos 4
authentificationworking with postgresql-6.4.2 and KTH-KRB Ebones(http://www.pdc.kth.se/kth-krb) on a dec alpha running DU 4.0D using the native compiler. Thefollowingpatch does the trick.The rationale behind this is as follows. The KTH-KRB code header filesdefineslots of lengths like INST_SZ,REALM_SZ and KRB_SENDAUTH_VLEN. It also hasahabit of doing things like chararray[LENGTH] = '\0'to ensure null terminated strings. In my instance this just happens toblatthe kerberos principal instance string leading to error like pg_krb4_recvauth: kerberos error: Can't decode authenticator(krb_rd_req)The application code that comes with KTH-KRB uses "KRB_SENDAUTH_VLEN +1" andsometimes uses "INST_SZ + 1" so it seems safest to put that 1 charbuffer inthe appropriate place.Rodney McDuff
