Final update, in case anyone else ever bumps into this: After digging deeper around what turned out to be a bit of a red herring (SSSD), I stumbled across a rather simple issue relating to using numeric only usernames, with a solution detailed at http://lists.x2go.org/pipermail/x2go-user/2015-April/003159.html
That one quick change to support numeric usernames in x2gosqlitewrapper.pl later and everything started working.
