This should cause the host TM>ticket to work correctly on -CURRENT. It's "my box approved". Does not work. I rebuilt my system with today's sources to be sure, removed my patches to the two library makefiles and rebuilt nss_ldap with your patch. I get: # ls -l dlopen: /usr/lib/libgssapi_spnego.so.10: Undefined symbol "GSS_C_NT_HOSTBASED_SERVICE" /libexec/ld-elf.so.1: /usr/lib/libgssapi_krb5.so.10: Undefined symbol "gss_oid_equal" Basically on everything I enter. Luckily vi still works :-) I saw that the configuration script claims not to find gss_krb5_ccache_name in -lgssapi or -lgssapi_krb5. This is because the test program for -lgssapi_krb5 links only to gssapi_krb5 but not to gssapi and so gets a lot of errors. I fixed this by adding gssapi, but the final result was the same. harti
