Comment 4 for bug 1850283

as matthias has explained, there is license information that only shipped in the python2 package, but referenced from the python3 package, hence a hard dependency is there.

However, the python3-ldap package should be usuable under python3 just fine in the mean time.

You are disliking the fact that python2 is pulled in at all, right? But python3-ldap otherwise works fine under python3 for you in Bionic?
