Hi, I'm trying to setup samba 3.0.14a as domain member on AIX 5.3. My test environment is: - PDC and ldap master on RH8.0 (samba 3.0.14a, openldap 2.1.29) - Ldap slave on FC3 (openldap 2.2.13) - Samba domain member on FC4 (samba 3.0.14a) - XP clients - and Samba domain member on AIX 5.3 (samba 3.0.14a) This is what I did: - Compiled samba ./configure --with-fhs --with-quotas --with-syslog --with-utmp \ --with-libsmbclient --with-acl-support \ --with-shared-modules=idmap_rid --enable-cups=yes \ --with-libiconv=/usr/local --with-ads=no successfully with gcc (gcc-3.3.2-5) or vac (7.0) against openldap 2.2.27 and libiconv 1.9.2 (see: http://lists.samba.org/archive/samba/2005-May/105333.html) - Client ldap setup on AIX with secldapclntd or nss_ldap-239 (nss_ldap see: http://bugzilla.padl.com/show_bug.cgi?id=202) This is what works on the aix domain member: - smbpasswd -w <secret> - net rpc join - net rpc info - net groupmap list - id <user> - lsuser <user> - lsgroup <group> - wbinfo -g - wbinfo -u - wbinfo -t - passwd <user> (only with secldapclntd) - smbpasswd <user> - ssh, telnet, rlogin from clients to aix domain member server - anonymous connects via smbbclient -Llocalhost -U% My samba configuration is: [global] workgroup = DOMAIN password server = * socket options = SO_RCVBUF=8192 SO_SNDBUF=8192 enable privileges = yes wins server = 192.168.xx.xx create mask = 0644 unix charset = ISO-8859-15 display charset = ISO-8859-15 username map = /usr/local/samba/etc/samba/username.map security = domain passdb backend = ldapsam:"ldap://ldap2 ldap://ldap1" ldap admin dn = uid=admin,dc=example,dc=com ldap suffix = dc=example,dc=com ldap user suffix = ou=people ldap group suffix = ou=groups ldap machine suffix = ou=systems ldap idmap suffix = ou=Idmap idmap backend = ldap:ldap://ldap1 idmap uid = 16777216-33554431 idmap gid = 16777216-33554431 winbind trusted domains only = Yes log file = /var/log/samba/log.%m.%a log level = 3 syslog = 0 max log size = 500 utmp = no This is what not works on aix domain member from Unix: - first try: smbbclient -Llocalhost -U<username> Password: Domain=[DOMAIN] OS=[Unix] Server=[Samba 3.0.14a] Sharename Type Comment --------- ---- ------- local Disk /usr/local with ACLs IPC$ IPC IPC Service (Samba 3.0.14a) ADMIN$ IPC IPC Service (Samba 3.0.14a) session setup failed: Call returned zero bytes (EOF) NetBIOS over TCP disabled -- no workgroup available - second, third ... try: smbbclient -Llocalhost -U<username> Password: session setup failed: Call returned zero bytes (EOF) - restart samba (goto: first try) This is what works on aix domain member from XP (after restarting samba (only first connect)): - open, save and rename files - changing acl's After disconnecting from aix member server, there are no further connections available (Error message: the networkname is not available). My samba domain member setup works perfectly with FC3 and FC4. I had the same problems (NetBIOS over TCP disabled -- no workgroup available) after updating from 3.0.10 to 3.0.11 on the rh8.0 pdc. Updating from nss_ldap-198 to nss_ldap-207 (rebuild from SRPM) solved the problem. Any ideas? Regards Carsten -- .
