The signature on the certificate was found to be invalid

Hi

I’m testing setting up Domino 8 server, and see if it still works with lower version for mail routing. I’ve found that it still works ok with Domino 6.

However, recently I tried to route with Domino 5, and found this error: “The signature on the certificate was found to be invalid, please check log file for details.”

Well, there’s only the same error message in the log file. I’ve certified both servers both ways. Tried deleting and recertify-ing, but to no success.

Can anyone enlighten me?

Thanks

This is due to the key strength on R8 servers being by default higher than 630-bit. The only way to get around this would be to lower the public key strength of the server ID on the R8 server. Open the server doc of the R8 server and click on the Administration tab, and set the “Maximum allowable key strength” and “Preferred key strength” fields to - Compatible with all releases - (630 bits). Save & close the server doc and restart the server. This will generate an adminp request to update the server ID. Once the adminp request is processed successfully, restart the server again.

Hi

Thks lots for your response. But it didn’t seem to work.

  1. I didn’t see any Admin requests being generated. However, when I look at the server.id file, I could see that it was updated

  2. I re-certify with the new server.id file

Log file still throwing the same error.

Anything else that I missed?

If you look on the Server doc’s Administration tab, what is the current key strength? Does this match what you see in the server ID? To confirm the latter, go to the Configuration tab and choose Tools → Certification → ID Properties → Your Identity → Your Certificates → Advanced Details.
