Hi, ( system Debian Squeeze 6.01 ) I've got problem with my LDAP-SAMBA server where samba is my PDC. I've configured libnss-ldap and libpam-ldap, smb.conf to enable the authentication between the both services. When using : getent passwd : i've got every people from the ldap server (same server) When i join a host XP to the domain, everything fine, it use the script of connection i use, mount share etc .. In fact where i've got the problem, is for the share files. I've in my smb.conf this line : /[partage] comment = Files exchange path = /partage writeable = yes admin users = @root valid users = @root @iatoss force directory mode = 0775 force create mode = 0775 /But it didn't work/, when you to enter the directory partage : if the user is from an other group, he can enter, modify etc ... So i've try several thing, like : #toto = test user made //valid users = toto / and here, only toto can enter, so my smb.conf is correct. Then i've try to see if my server could seen the group : getent group | grep iatoss Everything is fine, i see group and user inside. Am i missing something ? Thank you --
