Hello, I'm new in this group, and I can't found the answer of my problem anywhere. I read the HOWTO and explain something about it but I don't find the solution. Ok, the question is that I have SAMBA server with CUPS to share the printer and home between 34 linux and windowsXP machines. I put the drivers in a print$ share and all the people can install the driver only clicking in connect... The problem is that in some cases the printers default settings are overwritten for someone (I don't know who) and all the people receive this new parametres (for exemple not allow to print in both sides) and I have to go to the printer admin change the properties and then uninstall and install the printer. I create a printer admin that is not root or administrator, I tried to put the driver in read-only mode, but all fails. I use gentoo (kernel 2.6.17), samba (3.0.22-r3), cups (cups-1.2.6), openldap (2.3.30-r2). An extract of my smb.conf (only the relevant): [global] delete user from group script = /usr/sbin/smbldap-groupmod -x "% u" "%g" dns proxy = no netbios name = epsi netbios aliases = mthics dos charset = 850 Unix charset = ISO8859-1 local master = yes workgroup = nneint debug level = 3 os level = 65 ldap admin dn = cn=manager,dc=nneint,dc=com ldap passwd sync = Yes printing = cups printcap name = cups security = user add machine script = /usr/sbin/smbldap-useradd -w "%u" max log size = 500 log file = /var/log/samba/%m.log load printers = yes ldap user suffix = ou=People add group script = /usr/sbin/smbldap-groupadd -p "%g" socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 add user to group script = /usr/sbin/smbldap-groupmod -m "%u" "% g" domain master = yes encrypt passwords = yes passdb backend = ldapsam:ldap://127.0.0.1/ wins support = yes ldap delete dn = Yes ldap group suffix = ou=Groups ldap machine suffix = ou=People ldap suffix = dc=scytl_int,dc=com add user script = /usr/sbin/smbldap-useradd -m "%u" set primary group script = /usr/sbin/smbldap-usermod -g "%g" "% u" preferred master = yes domain logons = yes logon script = logon.bat logon path = \\nneinst\%U logon drive = H: logon home = \\%L\%U time server = yes admin users = administrator printer admin = printadmin min protocol = NT idmap uid = 10000-20000 idmap gid = 10000-20000 [printers] comment = All Printers path = /var/spool/samba browseable = no guest ok = yes writable = no printable = yes public = yes create mode = 0700 use client driver = no [print$] path = /etc/samba/drivers browseable = yes guest ok = no write list = printadmin read only = yes Thank you very match in advance
