MYAD, nothing from YAAD. However 'smbclient -L //localhost -U YAAD\\david' is working and printing shares on samba server, this I believe means interdomain trust is correctly set and recognized by samba ( from some level ). But when I try to connect to home share with YAAD\\david I get <log> 85 [2010/11/02 13:19:25.525993, 2] auth/auth.c:314(check_ntlm_password) 86 check_ntlm_password: Authentication for user [david] -> [david] FAILED with error NT_STATUS_NO_SUCH_USER <log> and <smbclient> rclus_01:~ # smbclient //localhost/homes -U YAAD\\david%secret tree connect failed: NT_STATUS_BAD_NETWORK_NAME <smbclient> How so? 'allow trusted domains' is enabled in smb.conf. 2. Am I using openldap as idmap backend right?
