I am having a problem getting active directory domain users to authenticate on my gentoo and debian systems with v3.0.25rc3 when it worked perfectly with v3.0.24. I am wondering if it is something in my configure options. Wbinfo returns users, groups and the rpc call test succeeds. The getent command only shows the local users. I have double checked my nsswitch.conf as well to make sure that it references winbind. Here is my configure command: ./configure --prefix=/usr --localstatedir=/var --with-configdir=/etc/samba --with-privatedir=/etc/samba --with-fhs --with-quotas --with-smbmount --with-pam --with-pam_smbpass --with-syslog --with-utmp --with-sambabook=/usr/share/swat/using_samba --with-swatdir=/usr/share/swat --with-shared-modules=idmap_rid --with-libsmbclient --with-automount --with-msdfs --with-ads --with-winbind --with-winbind-auth-challenge --with-manpages-langs=en --with-idmap --with-acl-support --with-ldap --with-swat --with-dnsupdate --with-cifsmount I have kept the same config that worked with the older version: [global] workgroup = MARKETSCAN realm = MARKETSCAN.COM server string = %h Samba Server, %v interfaces = eth0, lo bind interfaces only = Yes security = ADS log level = 3 log file = /var/log/samba/log.%m max log size = 50 client signing = Yes load printers = No os level = 2 preferred master = No local master = No domain master = No dns proxy = No ldap ssl = no socket address = 10.11.9.57 idmap uid = 10000-20000 idmap gid = 10000-20000 template homedir = /home/MARKETSCAN/%U template shell = /bin/bash winbind enum users = Yes winbind enum groups = Yes winbind use default domain = Yes [homes] comment = Home Directory for %U path = /home/MARKETSCAN/%U valid users = %D\%U create mask = 0700 directory mask = 0700 browseable = No vfs objects = readahead [public] comment = Public Share on %h path = /home/samba/public valid users = +users, "@MARKETSCAN\domain users" read only = No create mask = 0755 vfs objects = readahead I would really appreciate any and all help with this. Also my kernel version is 2.16.20 on gentoo and 2.6.18 on debian. Both have the same problem.
