Checking CRLs

Hello,

I was wondering what’s the best way to check crl validity + notifications using Nagios.

I googled and found the following info:
lists.grid.sinica.edu.tw/apwiki/ … 290006cb2d
osdir.com/ml/network.nagios.plug … 00002.html

Is there an updated info? did someone used Nagios to check CRLs?
How Nagios supports CRL checking?

10x.

I don’t know if this is the same file as one of the above, but take a look.
