Update Information:

Allow slower dirsrv startup with systemd:
- IPAdmin class will wait until dirsrv instance is available up to 10
seconds
- Helps with restarts during upgrade for ipa-ldap-updater
These enhancements are covered by FreeIPA ticket #2175, https://fedorahosted.org/freeipa/ticket/2175

- Fix pylint warnings from F16 and Rawhide

A Cross-Site Request Forgery (CSRF) flaw was found in FreeIPA due to a lack of
checking the Referer Header in the server (it is not set in the CLI utilities). If a remote attacker could trick a user, who was logged into the FreeIPA management interface, into visiting a specially-crafted URL, the attacker could perform FreeIPA oonfiguration changes with the privileges of the logged in
user.

CVE-2011-3636
Fixes SELinux issue in ipa_kpasswd preventing users from changing passwords.
Introduced upgrade script to recover existing configuration after systemd
migration
as user has no means to recover FreeIPA from systemd migration
- Upgrade script:
- recovers symlinks in Dogtag instance install
- recovers systemd configuration for FreeIPA's directory server
instances
- recovers freeipa.service
- migrates directory server and KDC configs to use proper keytabs for systemd
services
