I am currently using 2.0.7 on a Solaris 8 box, using password authentication via a W2K Domain Controller. Compiled up the new version (without winbind) and installed into a new directory. Used smbpasswd to join the machine to the domain, which was successful and started samba. Whenever I try to connect to a share on the solaris box, I get the following error in the samba log file: connect_to_domain_password_server: unable to setup the PDC credentials to machine DOMCTRL1. Error was: NT_STATUS_ACCESS_DENIED. If I edit the smb.conf file and set "encrypt passwords" to No, it works OK. Here is the smb.conf file for info [global] workgroup = DOMAIN1 netbios name = SERVER1 security = DOMAIN encrypt passwords = Yes password server = domctrl1 log file = /var/samba/logs/log.%m max log size = 50 printcap name = /opt/samba/sambaprintcap os level = 0 comment = Samba Server on server1 oplocks = No utmp = Yes [smb207] comment = Product top level share using links path = /export/samba-2.0.7 write list = user1 create mask = 0774 directory mask = 0775 force directory mode = 0775 guest ok = Yes Reverting back to the 2.0.7 version works perfectly. Any hints or suggestions gratefully received. Paul.
