Good afternoon, In my attempt to get Squid on our SLES 11 box authenticating with Kerberos (negotiate), I used the following to re-configure: ./configure --prefix=/usr/local/squid --enable-cachemgr-hostname=sclthdq01w --enable-auth="negotiate" --enable-negotiate-auth-helpers="squid_kerb_auth" The "configure" appears to run without any issues. However, upon running "make all" I receive the following errors: squid_kerb_auth.c:507: error: implicit declaration of function âgss_display_nameâ make[5]: *** [squid_kerb_auth.o] Error 1 make[5]: Leaving directory `/tmp/squid-3.1.0.13/helpers/negotiate_auth/squid_kerb_auth' make[4]: *** [all-recursive] Error 1 make[4]: Leaving directory `/tmp/squid-3.1.0.13/helpers/negotiate_auth/squid_kerb_auth' make[3]: *** [all] Error 2 make[3]: Leaving directory `/tmp/squid-3.1.0.13/helpers/negotiate_auth/squid_kerb_auth' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/tmp/squid-3.1.0.13/helpers/negotiate_auth' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/tmp/squid-3.1.0.13/helpers' make: *** [all-recursive] Error 1 Any ideas?? As always, T.I.A. -Daniel
