Subject: [PATCH 104/104] ipa-server-mode: use lower-case user name for home
 dir

In older IPA server versions where the AD users where looked up by
winbind the user name component of the home directory path was always
lower case.  This still holds for IPA clients as well. To avoid
regression this patch makes the user name component lower case as well.

Fixes https://fedorahosted.org/sssd/ticket/2263
