[Samba] CIFS mount problems
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hello, We have `some` problems related to the samba daemon, or possibly with the Linux kernel CIFS filesystem. We have 2 server (for this example): - - Storage Server, running Samba 3.0.28a on Ubuntu Linux (Samba version 3.0.28a-1ubuntu4.4) with ldap authentication. - - Client, running Linux 2.6.24 as a XEN domU. This server mounts on demand user home directory's from the Storage Server (via pam_mount) Initially the mounts work normally but at some point all get disconnected, see below for an example. Eg. 1.

[Samba] Auth Problem
Hello, I have a problem related to user authentication: Users can not login from Windows workstations. I get the following error: The system could not log you in. Make sure your User Name and domain are correct then type your password again. Users can access shares, they are prompted for a user and password and it is ok. The same user and password does not work for login. What could be the problem? I've posted the logs and smb.conf at http://www.info.uvt.ro/~neagul/samba/ I want to mention that the server is a production server and was hit by a hardware failure. :-( I restored everything but it doesn't work.

[Samba] Home dirs problem
Hello, I have a question about mapping users home directory's to samba. The homedir layout is based on an old one used on NIS+ system. The structure is something like: /users /group1 /user1 /user2 ... /group2 /user3 ... /group3 /group3_1 /user4 ... /group3_2 ... /group4 /user5 How can I configure samba to use this home directory's? The user data is stored in LDAP (including the home directory and other information not related to samba: qmail-ldap, courier, etc) ? The only option I've found is something similar to: path = /home/%U Can samba retrieve the home directory from LDAP?
