ldap publisher_acl by hostname

[wesleyarthur]

It doesn't seem like the ldap section of the f_defaults.conf can handle specifying only web* minions like this:

publisher_acl:
  fred:
    - web*:
      - test.*
      - pkg.*

It ends up generating this and the salt master can't process it. It ends up turning into this wrapped in extra single quotes:

publisher_acl:
  fred:
     - '{'web*': ['test.*', 'pkg.*']}'

It should look something like this (without the single quotes on the ends):

publisher_acl:
  fred:
    - {'web*': ['test.*', 'pkg.*']}
