Hello! I are running samba4 (from git) on a debian wheezy machine and are experimenting with Oracle XE (in Windows XP). If I try with Windows Active Directory I can connect to Oracle, but when I try with samba4 I see following errors in samba log: [2012/11/07 21:18:55, 3] ../source4/auth/kerberos/krb5_init_context.c:80(smb_krb5_debug_wrapper) Kerberos: TGS-REQ Administrator at DOM.TEST.COM from ipv4:172.17.123.244:1192for JORDITESTA at DOM.TEST.COM [renewable, forwardable] [2012/11/07 21:18:55, 3] ../source4/kdc/db-glue.c:1389(samba_kdc_lookup_server) Failed to find an entry for JORDITESTA [2012/11/07 21:18:55, 3] ../source4/auth/kerberos/krb5_init_context.c:80(smb_krb5_debug_wrapper) Kerberos: Server not found in database: JORDITESTA at DOM.TEST.COM: no such entry found in hdb [2012/11/07 21:18:55, 3] ../source4/auth/kerberos/krb5_init_context.c:80(smb_krb5_debug_wrapper) Kerberos: Failed building TGS-REP to ipv4:172.17.123.244:1192 samba-tool spn list JORDITESTA$ jorditesta$ User CN=JORDITESTA,CN=Computers,DC=dom,DC=test,DC=com has the following servicePrincipalName: HOST/jorditesta.dom.test.com HOST/JORDITESTA I tried create an user with the name of the computer (without $) and assign it the "spn" but not works :( Any suggestions?
