Older Desktop Clients Not Allowed to Connect and Sync
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Because of various technical issues, desktop sync clients older than 1.7 are 
not allowed to connect and sync with the ownCloud server.

Windows Not Supported
^^^^^^^^^^^^^^^^^^^^^

The ownCloud 8 server is not supported on any version of Windows.

Enterprise 8.1 Only
-------------------

Sharepoint Drive SSL Not Verified
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

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.

ownCloud 8.0
------------
Remote Federated Cloud Share Cannot be Reshared With Local Users
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

When you mount a Federated Cloud share from a remote ownCloud server, you cannot re-share it with your local ownCloud users. (See :doc:`configuration_files/federated_cloud_sharing_configuration` to learn more about federated cloud sharing)

Windows Server Not Supported
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Windows Server is not supported in ownCloud 8.

PHP 5.3 Support Dropped
^^^^^^^^^^^^^^^^^^^^^^^

PHP 5.3 is not supported in ownCloud 8, and PHP 5.4 or better is required.

Disable Apache Multiviews
^^^^^^^^^^^^^^^^^^^^^^^^^

If Multiviews are enabled in your Apache configuration, this may cause problems 
with content negotiation, so disable Multiviews by removing it from your Apache 
configuration. Look for lines like this:: 

 <Directory /var/www/owncloud>
 Options Indexes FollowSymLinks Multiviews
 
Delete ``Multiviews`` and restart Apache.

.. https://github.com/owncloud/core/issues/9039

ownCloud Does Not Follow Symlinks
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

ownCloud's file scanner does not follow symlinks, which could lead to 
infinite loops. To avoid this do not use soft or hard links in your ownCloud 
data directory.

.. https://github.com/owncloud/core/issues/8976

No Commas in Group Names
^^^^^^^^^^^^^^^^^^^^^^^^

Creating an ownCloud group with a comma in the group name causes ownCloud to 
treat the group as two groups.

.. https://github.com/owncloud/core/issues/10983

Hebrew File Names Too Large on Windows
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

On Windows servers Hebrew file names grow to five times their original size 
after being translated to Unicode.

.. https://github.com/owncloud/core/issues/8938

Google Drive Large Files Fail with 500 Error
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Google Drive tries to download the entire file into memory, then write it to a 
temp file, and then stream it to the client, so very large file downloads from 
Google Drive may fail with a 500 internal server error.

.. https://github.com/owncloud/core/issues/8810

Encrypting Large Numbers of Files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

When you activate the Encryption app on a running server that has large numbers 
of files, it is possible that you will experience timeouts. It is best to 
activate encryption at installation, before accumulating large numbers of files 
on your ownCloud server.

.. https://github.com/owncloud/core/issues/10657


Enterprise 8.0 Only
-------------------

Sharepoint Drive SSL Not Verified
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

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.

No Federated Cloud Sharing with Shibboleth
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

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

.. https://github.com/owncloud/user_shibboleth/issues/28

Direct Uploads to SWIFT do not Appear in ownCloud
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

When files are uploaded directly to a SWIFT share mounted as external storage 
in ownCloud, the files do not appear in ownCloud. However, files uploaded to 
the SWIFT mount through ownCloud are listed correctly in both locations.

.. https://github.com/owncloud/core/issues/8633

SWIFT Objectstore Incompatible with Encryption App
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The current SWIFT implementation is incompatible with any app that uses direct 
file I/O and circumvents the ownCloud virtual filesystem. Using the Encryption 
app on a SWIFT object store incurs twice as many HTTP requests and increases 
latency significantly.

.. https://github.com/owncloud/core/issues/10900

App Store is Back
^^^^^^^^^^^^^^^^^

The ownCloud App Store has been re-enabled in oC 8. Note that third-party apps 
are not supported.

ownCloud 7 Release Notes
------------------------

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.

.. https://github.com/owncloud/core/issues/12647

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.
