Hi, Just been browsing through my cui config on a FR 3.0.11 outward facing server and found the following accounting detail logging ...... FreeRADIUS-Acct-Session-Start-Time = "Feb 1 2016 09:39:17 GMT" Module-Failure-Message = "regex failed: Found null in subject at offset 18. String unsafe for evaluation" Module-Failure-Message = "Failed retrieving values required to evaluate condition" Acct-Unique-Session-Id = "0ab90a46c2f04499b46b7d9265696856" Stripped-User-Name = "jcm1k" Realm = "DEFAULT" SQL-User-Name = "jcm1k" Chargeable-User-Identity = 0x ........ So, 1). Module-Failure-Message - never seen this in a debug log before. Assuming its something specific to FR 3.x. What's it associated with? 2). Chargeable-User-Identity = 0x Should I see this or should I see the whole string? A
