Title Prevent log entry in web.log on each page access caused by 2.0 cookies
Date Apr 28, 2021
Level Trivial Change
Class Bug Fix
Compatibility Compatible - no manual interaction needed
Checkmk versions & editions
1.6.0p24 Checkmk Raw (CRE), Checkmk Enterprise (CEE), Checkmk MSP (CME)

Users which have authentication cookies issued by a Checkmk 2.0 site caused a log entry on each page access in the web.log. The log message looked like this: Exception while checking cookie auth_[site]: ... ValueError: could not convert string to float:.

Since the authentication cookies of both versions are not compatible at all, we now silently skip processing the cookies of Checkmk 2.0 or newer.
