samba 3. on RedHat 8 Samba is running as a domain controller and is correctly authenticating domain logon and access to Samba shares from windows client machines. BUT. windows clients, both 9x and NT can not "always" access each others shares. for example: a windows XP or 9x machine can not always connect to a share on another Windows XP or 98 machine and vice versa but can always access the Samba Shares and can always logon to the domain. the problem is intermitent and only occurs on windows shares not our samba shares which work fine. somethies i can access and sometimes i get access denied. \\computer is not accessable. you might not have permission to use this network resource. contact... this is not a network problem! i am 100% sure of that. i am confident the share permissions and secutity are correctly set on the windows shares. this is confirmed in that sometimes i get access. Does anyone know whats might cause this behaviour? smb.conf----> [global] idmap backend =ldap:ldap://localhost passdb backend =ldapsam ;SAMBA LDAP declarations ldap suffix = dc=xxxxx,dc=org,dc=uk ldap machine suffix = ou=Computers ldap user suffix = ou=Users ldap admin dn = "cn=Manager,dc=xxxxx,dc=org,dc=uk" ldap ssl = No ldap delete dn = no workgroup = domainname netbios name = chaos server string = MF File Server security = user null passwords = yes encrypt passwords = yes ;passwd program = /usr/local/sbin/smbldap-passwd.pl -o %u ;passwd chat = *new*password* %n\n *new*password* %n\n *successfully* ;unix password sync = Yes add group script = /etc/samba/smbaddgrp.sh %g log file = /var/log/samba/%m.loglog level = 0 ; remember to lower the log level in real life max log size = 0 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 domain logons = yes os level = 255 preferred master = yes domain master = yes dns proxy = No wins support = yes public = no browseable = no writable = no logon path = \\%L\profiles\%U logon script = startup.bat logon home = \\%L\%U\docs\.profiles logon drive = H: interfaces = 192.168.57.200 [homes] comment = Home Directories path = /home/%U/docs read only = no writable = yes browsable = no various other shares....
