Perfect, I didn't find that, sorry. Searching for defaultMaxAgeInSeconds was not the best idea 🙁 .
@rp 5 mins are totally fine - to be honest I wanted to find a nice way to modify the preconfigured time for "predefined" SessionClaimValidators - and in our case we can increase this value to a mucher higher value than 5 min. Thanks again for your always quick and efficient help.
