HTTA-808 — OOB external authentication produces too long lines
When OOB authentication method is set to EXTERNAL, a list of authenticated users is provided by an external source. The list is passed to the authentication server in an HTTP request, one line per user. If a line (containing an IP address, a user name, and a list of groups) is too long, the authentication server cannot process the list and update the authentication information it provides to proxies.
