• Consider changing this wording – please check with Shihab for technical correctness first:
  "Only connections with the specified protocol types will be pooled."
  to:
  "Only connections with the specified protocol types will be allowed."

• Consider changing this wording – please check with Shihab for technical correctness first:
  "Only connections with the specified authentication types."
  to:
  "Only connections with the specified authentication types will be allowed."
