--- Comment #2 from Tobias Junghans tobias.junghans@veyon.io --- I've also seen this assertion triggered by LDAP client code using libldap (through KDE/kldap) when querying certain AD servers. However I was not yet able to identify the exact code path or server setup causing this issue. Removing the assertion – at the first glance – seems to make the application work the way it did with 2.4.x. However I'm not sure about possible leaks or other side effects.
