Description of problem:
Add a permission of type subtree
To specify the subtree, the textarea is smaller than FF, and is clumsy to enter
the subtree in that area and scroll up and down to enter it.
FF has a bigger textarea, which can also be resized.

Version-Release number of selected component (if applicable):
ipa-server-2.2.0-16.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. Add a permission of type subtree
2. enter subtree - say - idnsname=testrelm.com,cn=dns,dc=testrelm,dc=com


Actual results:
cannot see the full subtree data, have to scroll line up or down

Expected results:
be able to see the full text area, without having to scroll, or be able to
resize
