Description Sönke Schwardt-Krummrich univentionstaff 2016-10-21 12:34:40 CEST
The configured value of max_requests in radiusd.conf is too low and caused authentication problem in some customer environments. Currently the value is hardcoded to 1024.
Comment 1 Sönke Schwardt-Krummrich univentionstaff 2016-10-21 14:13:05 CEST
Please note that for each auth request a separate authhelper process is spawned. So if the current limit of 1024 is reached, 1024 helper processes were running.

Advisory: univention-radius.yaml

freeradius/conf/max_requests:
 The maximum number of requests which the server keeps track of. This should be 256 multiplied by the number of clients, e.g. With 4 clients, this number should be 1024. (Default: 1024)
