Unfortunately properly supporting version 1.1.1 is not as simple as
changing the version tag at the top of the capabilities to say 1.1.1.
There is probably not much more to it (I don't remember the differences)
and changing the version number may be enough to fool the ArcExplorer
client but shouldn't be considered a good practice.
Actually, I'm a bit surprised that you were unable to connect since you
wrote that both of your clients support WMS 1.0.0 (do they really?).
MapServer does support V1.0.0 if the clients ask for that version... so
if those clients did implement WMS version negociation properly then
they would have picked version 1.0.0. Note that very few clients
implement WMS version negociation properly, I don't even think our
MapLab package does... one more reason to not implement hacks in
MapServer but instead work on fixing the clients to adhere to the spec.
