Description of problem:
  When using "ipa-client-automount" to configure automount and NFS on an IPA client, the "Domain" option is added to the bottom of the /etc/idmapd.conf file.  Because this file is formatted into sections, the "Domain" option is placed in the [Translation] section, and not the [General] section of the configuration file.  ID mapping does not work correctly with the "Domain" option in the [Translation] section.  After manually moving the "Domain" option to the [General] section, ID mapping works correctly.

Version-Release number of selected component (if applicable):
ipa-client-3.0.0-42.el6.x86_64
nfs-utils-lib-1.1.5-9.el6.x86_64

How reproducible:
  This is reproducible every time "ipa-client-automount" is executed and /etc/idmapd.conf is modified.

Steps to Reproduce:
1. Install a fresh Red Hat Enterprise Linux 6 host and apply all updates.
2. Install the "ipa-client" package.
3. Join host to IPA domain using "ipa-client-install".
4. Configure automount and NFS using "ipa-client-automount".

Actual results:
# ipa-client-automount --server rhidm.example.com --location default
IPA server: rhidm.example.com
Location: default

Additional info:
 Before fixing /etc/idmapd.conf, several "mapping" errors are logged into /var/log/messages:
