Hi, In the Directory LDAP, I've setup an entry with the sambaDomain objectClass. I've configured the four attributes of this objectClass. But my problem with smbpasswd still occurs : smbpasswd -a test New SMB password: Retype new SMB password: NO user RID specified on account test, cannot store! ldapsam_add_sam_account: init_ldap_from_sam failed! Failed to add entry for user test. Failed to modify password entry for user test Thank you for your help, Rapha?l
