### PHP 5.6.11+ Breaks LDAP Wizard

PHP 5.6.11+ breaks the LDAP wizard with a ‘Could not connect to LDAP’ error. See https://github.com/owncloud/core/issues/20020.

### Manual LDAP Port Configuration

When you are configuring the LDAP user and group backend application, ownCloud may not auto-detect the LDAP server’s port number, so you will need to enter it manually.

### LDAP Search Performance Improved

Prior to 7.0.4, LDAP searches were substring-based and would match search attributes if the substring occurred anywhere in the attribute value. Rather, searches are performed on beginning attributes. With 7.0.4, searches will match at the beginning of the attribute value only. This provides better performance and a better user experience.

Substring searches can still be performed by prepending the search term with “*”.For example, a search for `te` will find Terri, but not Nate:

    occ ldap:search "te"

If you want to broaden the search to include Nate, then search for `*te`:

    occ ldap:search "*te"

Refine searches by adjusting your search attributes in the `User Search Attributes` form in your LDAP configuration on the Admin page. For example, if your search attributes are `givenName` and `sn` you can find users by first name + last name very quickly. For example, you’ll find Terri Hanson by searching for `te ha`. Trailing whitespaces are ignored.

### Protecting ownCloud on IIS from Data Loss

Under certain circumstances, running your ownCloud server on IIS could be at risk of data loss. To prevent this, follow these steps.

In your ownCloud server configuration file, `owncloud\config\config.php`, set `config_is_read_only` to true.

Set the `config.php` file to read-only.

When you make server updates `config.php` must be made writeable. When your updates are completed re-set it to read-only.

### Antivirus App Modes

The Antivirus App offers three modes for running the ClamAV anti-virus scanner: as a daemon on the ownCloud server, a daemon on a remote server, or an executable mode that calls `clamscan` on the local server. We recommend using one of the daemon modes, as they are the most reliable.

### “Enable Only for Specific Groups” Fails

Some ownCloud applications have the option to be enabled only for certain groups. However, when you select specific groups they do not get access to the app.

### Changes to File Previews

For security and performance reasons, file previews are available only for image files, covers of MP3 files, and text files, and have been disabled for all other filetypes. Files without previews are represented by generic icons according to their file types.

### 4GB Limit on SFTP Transfers

Because of limitations in `phpseclib`, you cannot upload files larger than 4GB over SFTP.

### “Not Enough Space Available” on File Upload

Setting user quotas to `unlimited` on an ownCloud installation that has unreliable free disk space reporting– for example, on a shared hosting provider– may cause file uploads to fail with a “Not Enough Space Available” error. A workaround is to set file quotas for all users instead of `unlimited`.

### No More Expiration Date On Local Shares

In older versions of ownCloud, you could set an expiration date on both local and public shares. Now you can set an expiration date only on public shares, and local shares do not expire when public shares expire.

### Zero Quota Not Read-Only

Setting a user’s storage quota should be the equivalent of read-only, however, users can still create empty files.

## Enterprise 7 Only

### No Federated Cloud Sharing with Shibboleth

Federated Cloud Sharing (formerly Server-to-Server file sharing) does not work with Shibboleth .

### Windows Network Drive

Windows Network Drive runs only on Linux servers because it requires the Samba client, which is included in all Linux distributions.

`php5-libsmbclient` is also required, and there may be issues with older versions of `libsmbclient`; see Using External Storage > Installing and Configuring the Windows Network Drive App in the Enterprise Admin manual for more information.

By default CentOS has activated SELinux, and the `httpd` process can not make outgoing network connections. This will cause problems with curl, ldap and samba libraries. Again, see Using External Storage > Installing and Configuring the Windows Network Drive App in the Enterprise Admin manual for instructions.

### Sharepoint Drive SSL

The SharePoint Drive app does not verify the SSL certificate of the SharePoint server or the ownCloud server, as it is expected that both devices are in the same trusted environment.

### Shibboleth and WebDAV Incompatible

Shibboleth and standard WebDAV are incompatible, and cannot be used together in ownCloud. If Shibboleth is enabled, the ownCloud client uses an extended WebDAV protocol

### No SQLite

SQLite is no longer an installation option for ownCloud Enterprise Edition, as it not suitable for multiple-user installations or managing large numbers of files.

### No App Store

The App Store is disabled for the Enterprise Edition.

### LDAP Home Connector Linux Only

The LDAP Home Connector application requires Linux (with MySQL, MariaDB, or PostgreSQL) to operate correctly.
