Any chance there is a plugin that will link to Dokuwiki?

I am having trouble finding all that I need from the Wiki Plugin alone.

Is there a way to use Wordpress as a login device that leads to a particular Password-Protected Dokuwiki? Or a way to have the systems share users.

For example.

I have 10 different Dokuwikis for 10 different workgroups.

A person logs in via my Wordpress Homepage and based on their login, it will log them into their respective Dokuwiki. Their login can be a general login to the Dokuwiki page. So that say 10 individual user ids on Wordpress leads to only 1 user ID on Dokuwiki and so forth.

Any chance anyone has any experience with this task?
