Description of problem:
if you try to opt out of ipa-host-net-manager, directory manager password prompt, the command produces traceback.  It does not appear to have any adverse affects.

But I can definitely see this happening often in the following situation.

Admin has kerberos credentials and assumes that is enough for the command, has to go find out what the directory manager's password is ... so interupts!


Version-Release number of selected component (if applicable):

freeipa-server-2.0-0.2011020113git613a3d0.fc14.i686

How reproducible:
always

Steps to Reproduce:
1.  ipa-host-net-manage enable | disable | status
2.  At prompt for Directory Manager password ...  <ctrl>+c
3.
  
Actual results:
# ipa-host-net-manage status
Directory Manager password: 

Traceback (most recent call last):
  File "/usr/sbin/ipa-host-net-manage", line 201, in <module>
    sys.exit(main())
  File "/usr/sbin/ipa-host-net-manage", line 195, in main
    conn.disconnect()
  File "/usr/lib/python2.7/site-packages/ipalib/backend.py", line 74, in disconnect
    self.id, threading.currentThread().getName()
StandardError: disconnect: 'context.ldap2_157230828' does not exist in thread 'MainThread'


Expected results:
no trace back and graceful interupt.
