Hi,

I'am trying to authenticate clients connecting to my server.

[06/Mar/2002 18:45:19 25124] [info]  Connection to child 3 established
(server hub-1.trema.com:443, client 66.54.34.7)

[Hint: No CAs known to server for verification?]

>From the error message I can imagine two problems:
- the client has not sent any certificate
- the client has sent an unknown certificate.

Can anybody help me sorting out this ?

A Google lookup retrieves a lot of  "OpenSSL: error:140890C7".
Most of the time, people have invoked the ClientAuthentication by
mistake.

Regards
