Good Morning/Afternoon/Evening. I'm a bit dejected at the moment as all my googleing / howto reading has brought me no joy, Apparently there are people out there who have successfully set up Samba as member server in M$ 2003 ADS. However I have miserably failed / given up. What I want to do is have my people print to a PDF printer on Linux using cups after which they will be emailed the doc using a package called Alambic. It works pretty well however I need a username to send the email to as the username is mapped to an email address in a config file. Is there possibly another way of having my users connect to the Samba Box with their domain user name ? The requirement is a single sign on to the domain where they will not be prompted to authenticate again to the Samba box. Please any help will be appreciated, Thanks Nic Ps. incase anyone is interested maybe I can still save the ADS project I'm using Samba 3.0.2pre1 Kerberos 1.3.1 Here is Samba Config [global] workgroup = domain realm = domain.co.za security = ads password server = 172.28.20.2 winbind use default domain = yes client use spnego = yes encrypt passwords = yes server string = %L Print Server (%v) winbind separator = + idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = yes winbind enum groups = yes template homedir = /home/winnt/%D/%U template shell = /bin/bash printcap name = cups load printers = yes printing = cups log file = /var/log/samba/log.%m max log size = 50 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 wins server = 172.28.20.2 dns proxy = yes krb5.conf [logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmind.log [libdefaults] ticket_lifetime = 24000 default_realm = DOMAIN.CO.ZA default_tgs_enctypes = des-cbc-md5 des-cbc-crc default_tkt_enctypes = des-cbc-md5 des-cbc-crc permitted_enctypes = des-cbc-md5 des-cbc-crc kdc_req_checksum_type = 2 checksum_type = 2 ccache_type = 1 forwardable = true proxiable = true dns_lookup_realm = false dns_lookup_kdc = false [realms] DOMAIN.CO.ZA = { kdc = server.domain.co.za admin_server = server.domain.co.za default_domain = DOMAIN.CO.ZA } [domain_realm] .server.domain.co.za = DOMAIN.CO.ZA server.domain.co.za = DOMAIN.CO.ZA Following received in Winbind log [2004/01/15 14:02:00, 1] libads/ads_ldap.c:ads_name_to_sid(64) name_to_sid: root not found [2004/01/15 14:02:00, 1] nsswitch/winbindd_group.c:winbindd_getgroups(960) user 'root' does not exist Following in Cleint log
