When connection between a master machine and future replica is not
sane, the replica installation may fail unexpectedly with
inconvenient error messages. One common problem is misconfigured
firewall.
This patch adds a program ipa-replica-conncheck which tests the
connection using the following procedure:
1) Execute the on-replica check testing the connection to master
2) Open required ports on local machine
3) Ask user to run the on-master part of the check OR run it
automatically:
a) kinit to master as default admin user with given password
b) run the on-master part using ssh
4) When master part is executed, it checks connection back to
the replica and prints the check result
This program is run by ipa-replica-install as mandatory part. It
can, however, be skipped using --skip-conncheck option.
ipa-replica-install now requires password for admin user to run
the command on remote master.

Ground rules on adding new schema Brand new schema, particularly when written specifically for IPA, should be added in share/*.ldif. Any new files need to be explicitly loaded in ipaserver/install/dsinstance.py. These simply get copied directly into the new instance schema directory. Existing schema (e.g. in an LDAP draft) may either be added as a separate ldif in share or as an update in the updates directory. The advantage of adding the schema as an update is if 389-ds ever adds the schema then the installation won't fail due to existing schema failing to load during bootstrap. If the new schema requires a new container then this should be added to install/bootstrap-template.ldif.
