Forum OpenACS Q&A: External identification of an oacs 4.0 site through oacs 3.2.5

I am still running my main site on oacs 3.2.5 and I don't really have the time to port it to 4.0 although this would be the best idea!

I heard about the external identification effort for dotLRN... Would it be possible to use this module to identify users from  my oacs 3.2.5 site? How far has this module been developed? Any other thoughts to solve my problem?

I haven't looked into this much, but the Gatekeeper package might be another option.
