Enterprise principals are currently most useful for the AD provider and
hence enabled here by default while for the other Kerberos based
authentication providers they are disabled by default.
If additional UPN suffixes are configured for the AD domain the user
principal stored in the AD LDAP server might not contain the real
Kerberos realm of the AD domain but one of the additional suffixes which
might be completely randomly chooses, e.g. are not related to any
existing DNS domain. This make it hard for a client to figure out the
right KDC to send requests to.
To get around this enterprise principals (see
http://tools.ietf.org/html/rfc6806 for details) were introduced.
Basically a default realm is added to the principal so that the Kerberos
client libraries at least know where to send the request to. It is not
in the responsibility of the KDC to either handle the request itself,
return a client referral if he thinks a different KDC can handle the
request or return and error. This feature is also use to allow
authentication in AD environments with cross forest trusts.

changed the data type the krb5_renew_interval to string.
function krb5_string_to_deltat is used to convert and allow delimiters

This patch adds support for new config options krb5_backup_server and
krb5_backup_kpasswd. The description of this option's functionality
is included in man page in one of previous patches.

For the time being, if krb5_server is not found, still falls back to
krb5_kdcip with a warning. If both options are present in config file,
krb5_server has a higher priority.

If the configuration option krb5_store_password_if_offline is set to
true and the backend is offline the plain text user password is stored
and used to request a TGT if the backend becomes online. If available
the Linux kernel key retention service is used.

* add forgotten ldap_dns_service option
* sync IPA and LDAP options (ldap_pwd_policy and ldap_tls_cacertdir)
* ldap_uri is no longer mandatory for LDAP provider - the default is to
use service discovery with no address set now. Ditto for krb5_kdcip
and ipa_server

Previously, the option krb5_kpasswd was only available if
'chpass_provider = krb5' was specified explicitly. Now it will be
available also if 'auth_provider = krb5'.
This option was also missing from the IPA options, so I have added
it there as well
