LDAP seems to be broken in alpine image

Hello,

Looks like there's something missing in alpine image:

I pushed up a fix. It should now work in latest-alpine (build still needs to finish; might take ~30m), but the 1.1.1-py3-alpine container will stay as-is. The next point release will fix the 1.1.2-py3-alpine container.
