Hallo,
so ist der normale Ablauf:
Session startet:
[07/29 11:41:52.882] INFO DS-7f113925c700[4] xxxxx xxxxxxx AuthWrapper.validateLogin#278 Session 676929fe17399f31a6e46ca1065c1bef99a started on device SEC1BDA497F3ABE3.
Session ist zu Ende:
[07/29 11:41:53.351] INFO DS-7f113925c700[4] xxxxx xxxxxxx AuthWrapper.logout#775 Session 676929fe17399f31a6e46ca1065c1bef99a logged off normally.
Das ist die "usage info"
[07/29 11:41:53.355] "192.168.1.91 192.168.1.35" DS-7f113925c700[4] "CN=xxxxxx xxxxxxx/O=xxxxxx" "
http://xxxxxx.xxxxxx.xx/mail%2xxxxxx.nsf?Sync_4_29_30" dm 200 473 "Android-SAMSUNG-SM-G390F/101.700" SEC1BDA497F3ABE3 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 14 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 "S2D Mail 14A"
Wenn also die Session abbricht (Session may not be closed properly) wird keine "usage info" geschrieben (No usage info available ...)
Normalerweise wird ein Fehlercode ausgegeben.
Z.B.:
408=Request Timeout (Device did not respond before the Server timed out the session),
409=Conflict (Device started a new session which caused this session to be aborted),
449=Exchange ActiveSync Provision Required First
500=Unknown Error,
503=Server Busy
Also am besten mal das Debugging für den betroffenen Benutzer aktivieren:
