Well, this is to be found in an updated version of sotamaps which has not yet gone live. We’re still waiting on the MT IT department to finalize the implementation of their own single-sign-on (SSO) system, since the newer sotamaps already implemented that back in June/July last year, and in fact relies on that system to establish user-rights to view/use certain areas of the site. From what I’ve heard very recently, the MT IT SSO solution is almost ready, so it shouldn’t be too long now…
I should add in the MT IT dept’s defence that they are having to attempt to incorporate this SSO system into a collection of very disparate systems, some of which are home-brew (the current sotawatch), and others being partly (http://www.sota.org.uk/) or wholly (this reflector) off-the-shelf software, making it difficult to incorporate the SSO. Sotamaps, on the other hand, has been built in its entirety by li’l ol’ me, so incorporation of the SSO was relatively straightforward.
