I am running Samba 3.0.35. When I run net ads join or net ads keytab create I see that the keytab file cannot be created. Here's a portion of the log: [2013/03/20 07:57:50, 3] libads/kerberos.c:(337) kerberos_secrets_store_des_salt: Storing salt "host/pitviper.DOMAIN at REALM" [2013/03/20 07:57:50, 2] libads/kerberos_keytab.c:(260) ads_keytab_add_entry: Using default system keytab: FILE:/etc/krb5/krb5.keytab [2013/03/20 07:57:50, 3] libads/kerberos_keytab.c:(184) smb_krb5_kt_add_entry: adding keytab entry for (host/pitviper.DOMAIN at REALM) with encryption type (1) and version (8) [2013/03/20 07:57:50, 1] libads/kerberos_keytab.c:(189) smb_krb5_kt_add_entry: adding entry to keytab failed (Cannot write to specified key table) [2013/03/20 07:57:50, 1] libads/kerberos_keytab.c:(346) ads_keytab_add_entry: Failed to add entry to keytab file [2013/03/20 07:57:50, 1] libads/kerberos_keytab.c:(508) ads_keytab_create_default: ads_keytab_add_entry failed while adding 'host'.
