[Mediawiki-l] address validation and editing rights

[Florian Effenberger]

Hi,

we just deployed a MediaWiki at The Document Foundation, running with
FastCGI. Everything seems to work like a charm, except one issue: I
have set

$wgEmailConfirmToEdit = true;

People complain that after they confirmed their account, they need to
log out, restart the browser and then wait five minutes until that
validation is accepted, otherwise - even after successful validation -
they see an error message stating they cannot edit without being
validated.

Is there some timeout or maintenance script running only all five
minutes that could cause this?

Thanks,
Florian
