# ownCloud 9.0 Server Administration Manual

# Installing and Configuring the Windows Network Drive App

The Windows Network Drive app creates a control panel on your Admin page for seamless mounting of SMB/CIFS file shares on ownCloud servers.

Any Windows file share, and Samba servers on Linux and other Unix-type operating systems use the SMB/CIFS file-sharing protocol. The files and directories on the SMB/CIFS server will be visible on your Files page just like your other ownCloud files and folders. They are labeled with a little four-pane Windows-style icon, and the left pane of your Files page includes a Windows Network Drive filter. Figure 1 shows a new Windows Network Drive share marked with red warnings. This indicates that ownCloud cannot connect to the share because it is not available, or there is an error in the configuration.

Files are synchronized bi-directionally, and you can create, upload, and delete files and folders. ownCloud server admins can create Windows Network Drive mounts, and optionally allow users to create their own personal Windows Network Drive mounts. The password for each mount is encrypted and stored in the ownCloud database, using a long random secret key stored in `config.php`. This allows ownCloud to access the shares when the users who own the mounts are not logged in.

## Installation

Enable the Windows Network Drive app on your ownCloud Apps page. Then there are a few dependencies to install.

You must install the ownCloud `php5-libsmbclient` binary; please refer to the README in your customer.owncloud.com account for instructions on obtaining it.

You also need the Samba client installed on your Linux system. This is included in all Linux distributions; on Debian, Ubuntu, and other Debian derivatives this is `smbclient`. On SUSE, Red Hat, CentOS, and other Red Hat derivatives it is `samba-client`.

## Additional Installation Steps

If your Linux distribution ships with `libsmbclient 3.x`, which is included in the Samba client, you may need to set up the HOME variable in Apache to prevent a segmentation fault. If you have `libsmbclient 4.1.6` and higher it doesn’t seem to be an issue, so you won’t have to change your HOME variable.

To set up the HOME variable on Ubuntu, modify the `/etc/apache2/envvars` file:

    unset HOME
    export HOME=/var/www

In Red Hat/CentOS, modify the `/etc/sysconfig/httpd` file and add the following line to set the HOME variable in Apache:

    export HOME=/usr/share/httpd

By default CentOS has activated SELinux, and the `httpd` process can not make outgoing network connections. This will cause problems with the `curl`, `ldap` and `samba` libraries. You’ll need to get around this in order to make this work. First check the status:

    getsebool -a | grep httpd
    httpd_can_network_connect --> off

Then enable support for network connections:

    setsebool -P httpd_can_network_connect 1

In openSUSE, modify the `/usr/sbin/start_apache2` file:

    export HOME=/var/lib/apache2

Restart Apache, open your ownCloud Admin page and start creating SMB/CIFS mounts.

## Creating a New Share

When you create a new SMB share you need the login credentials for the share, the server address, the share name, and the folder you want to connect to.

1. First enter the ownCloud mountpoint for your new SMB share. This must not be an existing folder.
2. Then enter which ownCloud users or groups get access to the share. The default is all users.
3. Next, enter the address of the server that contains the SMB share.
4. Then the Windows share name.
5. Then the root folder of the share. This is the folder name, or the `$user` variable for user’s home directories. Note that the LDAP `Internal Username Attribute` must be set to the `samaccountname` for either the share or the root to work, and the user’s home directory needs to match the `samaccountname`. (See User Authentication with LDAP.)
6. Then your login credentials.

You have four options for login credentials:

- User credentials. For admin-created global mountpoints; users must click on the share and then enter their personal credentials to access the share.
- Global credentials. Uses the credentials set in the Global credentials fields
- Login credentials is for users to connect to the mountpoint using their DOMAIN/login credentials; enter the domain in the Domain field.
- Custom Credentials. On admin-created global mountpoints, the admin may configure custom credentials to access the shares. For example, the admin uses a single system account to mount company folders for all users. The folder permissions are mapped with the system account permissions. When users create a share on their Personal pages, custom credentials are only for that mountpoint. For example, User A creates a mountpoint that is accessible with User B’s credentials.

When you’re finished click the Save button.

Note

When you create a new mountpoint using Login credentials you must log out of ownCloud, and then log back in so you can access the share. You only have to do this the first time.

## Personal SMB Mounts

Users create their own personal SMB mounts on their Personal pages. These are created the same way as Admin-created shares. Users have only two options for login credentials:

- Personal Credentials.
- Custom Credentials
