Hello, Joining a NT-Domain with the command "smbpasswd -j DOM -r PDCname -U Admin" will result in joining the NT-Domian. " wbinfo -u " shows the NT-accounts succesfully. But authenticating users with winbind on the NT-PDC fails with a "access denied" message in the system-tab of the eventviewer of NT-PDC. Creating the machineaccount within Servermanager first and then joining the domain by typing "smbpasswd -j DOM" solve the Problem. -SuSE Linux 7.0 s390 -Kernel 2.2.16 -built with: configure --with-winbind --host=s390-ibm-linux make nsswitch make nsswitch/pam_winbind.so make make install regards Dirk Angenendt Informations Verarbeitungs Zentrum Telefon +49 30 3031 4556
