Steps to reproduce:

1. Create host group "HG 1 space"
2. Create host group "HG     1 space" (watch whitespaces)
3. View host group list

Screenshots:

Result: visual identical names, but for different group.

Expecting: visual not identical names OR reject creating visual identical names (after whitespace trimming)

Creates ambiguity of choice and the possibility of manipulating access rights (counting on inattention)
