We should just lower the default expiration date from 30y to a more sane value.

  • Icinga Version changed from 2 to 2

Hm, apparently it only affects the git master, not 2.3.10 and also not only 32bit centos5, also x64.

And it seems, only certificates generated with new-cert, but not the ones coming from 'api setup'. strange.

  • Subject changed from openssl certificate not after overflow on rhel5 32 bit to openssl certificate not after overflow on rhel5
  • Status changed from Assigned to Resolved
  • Done % changed from 0 to 100

No idea which change introduced the overflow, but apparently I read an article where setting the expiration that long isn't a good idea either. Lowering the value to 15y solves the issue.
