Description of problem:

auth.allow seems to be limited to 1024 chars, at least in 3.2.5

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

glusterfs 3.2.5, perhaps in later versions as well

How reproducible:

at least always in 3.2.5

Steps to Reproduce:
1. Create an auth.allow entry with enough IP addresses to exceed 1024 chars
2. auth.allow is truncated and anything past 1024 chars is not read/enforced or given access
  
Actual results:

auth.allow is truncated and anything past 1024 chars is not read/enforced or given access

Expected results:

auth.allow should not be truncated or should be dynamically allocated (unlimited length)

Additional info:

If you can add the ability for auth.allow to read hostname wildcards, a superset of the feature requested in bug 861932 comment 2 then that would help greatly too. I could easily reduce my auth.allow list to only a few hostname wildcards and get rid of most of the ip's and ip wildcards.
