Use this operation to log in to a repository. The Login operation authenticates the user name and password for a specified repository. The client application must call this operation before calling any other operations. After calling the Login operation, the web service client application can call any Batch web service operations.

The Login operation requires a repository name, user name, and password. It returns an encrypted session ID. The repository must be in the same domain as the Web Services Hub.

The following table describes the parameters for this operation:

The session ID expires after a period of inactivity. Configure the

SessionExpiryPeriod

advanced property of the Web Services Hub to specify the length of time allowed for inactivity before the session expires. You can configure the Web Services Hub advanced properties in the Administrator tool.

The Web Services Hub caches the user name and password at the start of a session. The Web Services Hub uses the cached user name and password for login authentication until the session expires. Changes to the user account do not affect authentication until the session expires. If you delete or disable a user account, the user account is not deleted or disabled until the session expires. If the user account is locked, the locked user can send requests until the session expires.
