Apps Config.php Parameters

Introduction

This document describes parameters for apps maintained by ownCloud that are not part of the core system. All keys are only valid if the corresponding app is installed and enabled. You must copy the keys needed to the active config.php file.

Multiple configuration files

ownCloud supports loading configuration parameters from multiple files. You can add arbitrary files ending with .config.php in the config/ directory.

Example:

You could place your email server configuration in email.config.php. This allows you to easily create and manage custom configurations or to divide a large complex configuration file into a set of smaller files. These custom files are not overwritten by ownCloud, and the values in these files take precedence over config.php.

ownCloud may write configurations into config.php. These configurations may conflict with identical keys already set in additional config files. Be careful when using this capability!

App: Metrics

Note: This app is for Enterprise Customers only.

Possible keys: metrics_shared_secret STRING

Secret to use the Metrics dashboard

You have to set a Metrics secret to use the dashboard. You cannot use the dashboard without defining a secret. You can use any secret you like. In case you want to generate a random secret, use the following example command: echo $(tr -dc 'a-z0-9' < /dev/urandom | head -c 20) It is also possible to set this secret via an occ command which writes key and data to the config.php file. Please see the occ command documentation for more information.

Code Sample

'metrics_shared_secret' => 'replace-with-your-own-random-string',

App: Microsoft Office Online (WOPI)

Note: This app is for Enterprise Customers only.

Possible keys: wopi.token.key STRING

Possible keys: wopi.office-online.server URL

Possible keys: wopi_group STRING

Random key created by the ownCloud admin

This is a random key created by the ownCloud admin. This key is used by ownCloud to create encrypted JWT tokens for the communication with your Microsoft Office Online instance.

You can use the following example command to generate a random key: echo $(tr -dc 'a-z0-9' < /dev/urandom | head -c 20)

Code Sample

'wopi.token.key' => 'replace-with-your-own-random-string',

Microsoft Office Online instance URL

This is the URL of the Microsoft Office Online instance ownCloud communicates with. Keep in mind that you need to grant communication access at your Microsoft Office Online instance with this ownCloud instance. For further information, read the ownCloud documentation.

Code Sample

'wopi.office-online.server' => 'https://your.office.online.server.tld',

Define the group name for users allowed to use Microsoft Office Online

Restrict access to Microsoft Office Online to a defined group. Please note, only one group can be defined. Default = empty = no restriction.

Code Sample

'wopi_group' => '',

App: Microsoft Teams Bridge

Possible keys: msteamsbridge ARRAY

Sub key: loginButtonName STRING

Login Button Label

This key is necessary for security reasons. Users will be asked to click a login button each time when accessing the ownCloud app after a fresh start of their Microsoft Teams app or after idle time. This behavior is by design. The button name can be freely set based on your requirements.

Code Sample

'msteamsbridge' => [
   "loginButtonName" => "Login to ownCloud with Azure AD",
],

App: OpenID Connect (OIDC)

Possible keys: openid-connect ARRAY

Configure OpenID Connect - all possible sub-keys

You have to use the main key together with sub keys listed below, see code samples.

allowed-user-backends

Limit the users which are allowed to login to a specific user backend - e.g. LDAP ('allowed-user-backends' ⇒ ['LDAP'])

auth-params

Additional parameters which are sent to the IdP during the auth requests

autoRedirectOnLoginPage

If true, the ownCloud login page will redirect directly to the Identity Provider login without requiring the user to click a button. The default is false.

auto-provision

If auto-provision is setup, an ownCloud user will be created if not exists, after successful login using openid connect. The config parameters mode and search-attribute will be used to create a unique user so that the lookup mechanism can find the user again. This is where an LDAP setup is usually required. If auto-provision is not setup or required, it is expected that the user exists and you MUST declare this with ['enabled' ⇒ false] like shown in the Easy Setup example. auto-provision holds several sub keys, see the example setup with the explanations below.

insecure

Boolean value (true/false), no SSL verification will take place when talking to the IdP - DO NOT use in production!

loginButtonName

The name as displayed on the login screen which is used to redirect to the IdP. By default, the OpenID Connect App will add a button on the login page that will redirect the user to the Identity Provider and allow authentication via OIDC. This parameter allows the button text to be modified.

mode

This is the attribute in the owncloud accounts table to search for users. The default value is email. The alternative value is: userid.

post_logout_redirect_uri

A given URL where the IdP should redirect to after logout.

provider-params

Additional config array depending on the IdP to be entered here - usually only necessary if the IdP does not support service discovery.

provider-url, client-id and client-secret

Variables are to be taken from the OpenID Connect Provider’s setup. For the provider-url, the URL where the IdP is living. In some cases (KeyCloak, Azure AD) this holds more than just a domain but also a path.

redirect-url

The full URL under which the ownCloud OpenId Connect redirect URL is reachable - only needed in special setups.

scopes

Enter the list of required scopes depending on the IdP setup.

search-attribute

The attribute which is taken from the access token JWT or user info endpoint to identify the user. This is the claim from the OpenID Connect user information which shall be used for searching in the accounts table. The default value is email. For more information about the claim, see https://openid.net/specs/openid-connect-core-1_0.html#Claims.

token-introspection-endpoint-client-id

Client ID to be used with the token introspection endpoint.

token-introspection-endpoint-client-secret

Client secret to be used with the token introspection endpoint.

use-access-token-payload-for-user-info

If set to true any user information will be read from the access token. If set to false the userinfo endpoint is used (starting app version 1.1.0).

use-token-introspection-endpoint

If set to true, the token introspection endpoint is used to verify a given access token - only needed if the access token is not a JWT. If set to false, the userinfo endpoint is used (requires version >= 1.1.0) Tokens which are not JSON WebToken (JWT) may not have information like the expiry. In these cases, the OpenID Connect Provider needs to call on the token introspection endpoint to get this information. The default value is false. See https://tools.ietf.org/html/rfc7662 for more information on token introspection.

Easy setup

App: Richdocuments

Possible keys: collabora_group STRING

Define the group name for users allowed to use Collabora

Please note, only one group can be defined. Default = empty = no restriction.

Code Sample

'collabora_group' => '',

App: Windows Network Drive (WND)

Note: This app is for Enterprise Customers only.

Possible keys: wnd.listen.reconnectAfterTime INTEGER

Possible keys: wnd.logging.enable BOOL

Possible keys: wnd.storage.testForHiddenMount BOOL

Possible keys: wnd.in_memory_notifier.enable BOOL

Possible keys: wnd.permissionmanager.cache.size INTEGER

Possible keys: wnd2.cachewrapper.ttl INTEGER

Possible keys: wnd.activity.registerExtension BOOL

Possible keys: wnd.activity.sendToSharees BOOL

Mandatory listener reconnect to the database

The listener will reconnect to the DB after given seconds. This will prevent the listener to crash if the connection to the DB is closed after being idle for a long time.

Code Sample

'wnd.listen.reconnectAfterTime' => 28800,

Enable additional debug logging for the WND app

Code Sample

'wnd.logging.enable' => false,

Check for visible target mount folders when connecting

Ensure that the connectivity check verifies the mount point is visible.

This means the target folder is NOT hidden. Setting this option to false can speed up the connectivity check by skipping this step. It will be the admin’s responsibility to ensure the mount point is visible. This setting will affect all the WND mount points.

Code Sample

'wnd.storage.testForHiddenMount' => true,

Enable or disable the WND in-memory notifier for password changes

Having this feature enabled implies that whenever a WND process detects a wrong password in the storage - maybe the password has changed in the backend - all WND storages that are in-memory will be notified in order to reset their passwords if applicable and not to requery again.

The intention is to prevent a potential password lockout for the user in the backend. As with PHP lower than 7.4, this feature can take a lot of memory resources. This is because WND keeps the storage access and its caches in-memory. With PHP 7.4 or above, the memory usage has been reduced a significantly. Alternatively, you can disable this feature completely.

Code Sample

'wnd.in_memory_notifier.enable' => true,

Maximum number of items for the cache used by the WND permission managers

A higher number implies that more items are allowed, increasing the memory usage.

Real memory usage per item varies because it depends on the path being cached. Note that this is an in-memory cache used per request. Multiple mounts using the same permission manager will share the same cache, limiting the maximum memory that will be used.

Code Sample

'wnd.permissionmanager.cache.size' => 512,

TTL for the WND2 caching wrapper

Time to Live (TTL) in seconds to be used to cache information for the WND2 (collaborative) cache wrapper implementation. The value will be used by all WND2 storages. Although the cache isn’t exactly per user but per storage id, consider the cache to be per user, because it will be like that for common use cases. Data will remain in the cache and won’t be removed by ownCloud. Aim for a low TTL value in order to not fill the memcache completely. In order to properly disable caching, use -1 or any negative value. 0 (zero) isn’t considered a valid TTL value and will also disable caching.

Code Sample

'wnd2.cachewrapper.ttl' => 1800,  // 30 minutes

Enable to push WND events to the activity app

Register WND as extension into the Activity app in order to send information about what the wnd:process-queue command is doing. The activity sent will be based on what the wnd:process-queue detects, and the activity will be sent to each affected user. There won’t be any activity being sent outside of the wnd:process-queue command. wnd:listen
wnd:process-queue + activity app are required for this to work properly. See wnd.activity.sendToSharees below for information on how to send activities for shared resources. Please consider that this can have a performance impact when changes are sent to many users.

Code Sample

'wnd.activity.registerExtension' => false,

Enable to send WND activity notifications to sharees

The wnd:process-queue command will also send activity notifications to the sharees if a WND file or folder is shared (or accessible via a share). It’s REQUIRED that the wnd.activity.registerExtension flag is set to true (see above), otherwise this flag will be ignored. This flag depends on the wnd.activity.registerExtension and has the same restrictions.

Code Sample

'wnd.activity.sendToSharees' => false,

App: Workflow / Tagging

Note: This app is for Enterprise Customers only.

Possible keys: workflow.retention_engine STRING

Provide advanced management of file tagging

Enables admins to specify rules and conditions (file size, file mimetype, group membership and more) to automatically assign tags to uploaded files. Values: tagbased (default) or userbased.

Code Sample

'workflow.retention_engine' => 'tagbased',
