Authentication parameters

In MobiLink scripts, authentication parameters can be specified using named parameters. If named parameters are used, the authentication parameters must be prefaced with the letter a, such as {ml a.1}. The parameters must be numbers starting at 1, with a limit of 255. Each parameter can be a maximum of 4000 bytes. The values are sent up from MobiLink clients.

When used in the authenticate_* scripts, authentication parameters pass authentication information.

Authentication parameters can be used in all other events (except begin_connection and end_connection) to pass information from MobiLink clients. This technique is a convenient way to do something that you could otherwise do by uploading rows to a table. With authentication parameters the values are available prior to the table's upload events.

On SQL Anywhere remotes, you pass the information with the dbmlsync -ap option. On UltraLite remotes, you pass the information with auth_parms and num_auth_parms.
