After each time I restart winbind I have to rejoin the domain in order for "wbinfo -t" to succeed or "smbclient //server/share -U user" to succeed. I am running: samba-3.0.10-0.1 (SuSE 9.1 Pro) heimdal-0.6.1rc3-55.9 The following error is returned from "wbinfo -t": FileTest:~ # wbinfo -t checking the trust secret via RPC calls failed error code was NT_STATUS_INVALID_COMPUTER_NAME (0xc0000122) Could not check secret I also get a "NT_STATUS_INVALID_COMPUTER_NAME" error from smbclient .... The following is written to the log: /var/log/samba/log.winbindd [2005/02/17 21:29:24, 0] rpc_client/cli_netlogon.c:cli_nt_setup_creds(256) cli_nt_setup_creds: request challenge failed Clock skew does not appear to be the cause: FileTest:~ # net ads info LDAP server: 192.168.1.201 LDAP server name: win_ads1 Realm: MYCOMPANY.COM Bind Path: dc=MYCOMPANY,dc=COM LDAP port: 389 Server time: Thu, 17 Feb 2005 21:32:19 GMT KDC server: 192.168.1.201 Server time offset: 69 Thanks for any guidance in resolving this issue.
