Reorder section to be more logical.

Based on r1553469.

This fixes an example which contains spaces in a LDAP group name (i.e. cn=Temporary Employees,o=Airius)

I've also synch with trunk:
   -  add some " to improve syntax highlight
   - use AuthLDAPUrl in stead of AuthLDAPURL in order to have syntax highlight work
