I'm wanting to use the information stored in xf_user and xf_user_authenticate for moodle authentication. I think building a view with the two tables would allow me to use the Moodle external database plugin. What security risk might I run into ? DB name Name of the database itself DB user Username with read access to the database Password Password matching the above username Table Name of the table in the database Username field Name of the field containing usernames Password field Name of the field containing passwords Password format Specify the format that the password field is using. MD5 hashing is useful for connecting to other common web applications like PostNuke.
