![]() ![]() Please note that the actual authentication supported by any specific dCache instance is controlled by the server’s configuration, so you may not have access to all these authentication options. This section describes the different authentication options that dCache supports. When using TLS-based authentication, the client makes requests without any Authorization HTTP request headers. This allows the client to authenticate without revealing all information, allowing the authentication to take place before the encrypted connection is established. Unlike bearer tokens, this process is iterative. During this TLS handshake, the client can authenticate. After establishing the TCP connection, a TLS handshake takes place to ensure the connection is encrypted. SSL/TLS authentication, in contrast to Authorization header authentication, happens before the HTTP requests. Encryption is mandatory when using bearer tokens however, even with transport encryption (such as SSL/TLS), bearer tokens are inherently risky, and often use restrictions to reduce the impact should they be stolen. This is simpler than the alternatives, but comes at a cost: any agent able to observe the HTTP request has the token and can subsequently impersonate the valid client. Several of these options are available to dCache clients.īroadly speaking there are two ways of authenticating: the Authorization HTTP request header (which often uses some bearer token) and through SSL/TLS.Ī bearer token is a token that requires no interaction to authenticate: supplying the token as part of the request is sufficient. HTTP is very flexible in how it handles authentication, with may different ways a client can prove its identity. #Webdav client cache code#Perhaps the most common is password based authentication, where the client proving to the server that it knows some secret code supplied by the user. AuthenticationĪuthentication is the process where the client proves the identity of the user. Other clients should also work and you should not read these choices as an endorsement of those clients over others. In this chapter, we will use curl to illustrate most HTTP operations, and rclone as a specific WebDAV client. Although WebDAV is less popular, there are still many clients from which you can choose. #Webdav client cache download#In simple terms, HTTP allows a client to upload, download and delete files, while WebDAV allows filesystem-like operations, such as to rename files and list directory contents.ĭue to its overwhelming popularity, there are many HTTP clients. Web Distributed Authoring and Versioning (WebDAV) is an extension of the Hypertext Transfer Protocol (HTTP) that allows clients to perform remote Web content authoring operations. When you want to use one of the connections in, e.g., caldav, simply note the ID in the first column and configure a new calendar with the ID webdav://7 to connect to the WebDAV connection with ID 7.From the corresponding English language Wikipeda entry, The button “Resync” first deletes all local entries and performs a synchronisation afterwards. ![]() If it went successful, you can enable the connection (Dropdown to “active” and then click on “Modify Connection”).Ĭurrently, it is not possible to change the username and password.Īttention Most of the buttons do not ask for confirmation! If you click on “Delete”, the connection is deleted! The button “Empty” deletes all entries from the server. Keep the connection disabled and click on “Force Sync”. This is due to the possibility of a large initial sync. This is required for ICS feeds.Īfter adding a connection, it is disabled by default. If auto-discovery fails, you can manually add a new connection in the lower right corner. If it is successful, you get a list with all discovered calendars/addressbooks and can select the ones you would like to add. You can try auto-discovery first by providing only the minimal information set in the lower left corner (WebDAV only). Go the Admin → WebDAV Connection Setup and add a new connection. Only an admin can configure WebDAV connections. ![]()
