Description of problem:
When running ipa-client-install, the ipaclient-install.log shows:
    getent passwd admin
The 'admin' username is hard-coded, so this check will fail if the admin
account has been renamed.

This check should use the username that was entered earlier in the install
process at the prompt:
    User authorized to enroll computers:
as this user is guaranteed to exist.


Version-Release number of selected component (if applicable):
ipa-client-2.1.3-7.el5


How reproducible:
Always


Steps to Reproduce:
1. Perform installation with 'ipa-client-install'
2. Review log in /var/log/ipaclient-install.log


Actual results:
Observe lines in log:
    DEBUG args=getent passwd admin
    DEBUG stdout=
    DEBUG stderr=


Expected results:
Username 'admin' should show the username that was input at the prompt earlier
in the process.
