Good day. The server is a Solaris 9 Sparc, fully patched, running 3.0.25a. The backend is just the smbpasswd file, security = user. This has worked for simple file sharing as long as I can remember. gcc 3.4.6 was the compiler and it was built with: ./configure --prefix=/scratch/samba --with-acl-support=yes When I set a password for a user with smbpasswd, if the password is <= 8 characters, smbclient can access the user's directory fine from any machine. If, however, the password is 9 characters or greater, the Solaris smbclient from 3.0.25a works fine, but any Linux smbclient fails with: session setup failed: NT_STATUS_LOGON_FAILURE Thanks for any direct help or for any pointers. Cheers, Zube
