I'd prefer the use of 'with' in the RedHatDirectoryService:
# check limits.conf
need_limits = True
with open("/etc/security/limits.conf") as f:
  for line in f:
      sline = line.strip()
      if not sline.startswith(DS_USER):
          continue
      if sline.find('nofile') == -1:
          continue
      # ok we already have an explicit entry for user/nofile
      need_limits = False

... and ...

with open("/etc/sysconfig/dirsrv", "a+") as f:
    f.write('ulimit -n %s\n' % str(num))
