Title: #128: Fix group renaming issue when "id_provider = ldap" is set

"""
There was a recent confusion about this PR. I thought that this should actually have been marked as changes requested to solve @lslebodn 's comment from Oct 2 that mentioned expiring the entries from the memory cache. Other than that, this PR looks OK to me and there is even a test in a different PR.
