rlm_eap: SSL error

Hello,

I receive the following errors :
Error: rlm_eap: SSL error error:00000000:lib(0):func(0):reason(0)
...
Error: Trying to look up name of unknown client 127.0.0.1.
...
(please see hereafter more complete log)

I'm confused by the fact that this config was working fine few days.
Apparently only an upgrade of linux distribution (Fedora 5-->6) was made
since last succesful login.

Thanks for any clue / idea.
Cheers,
Bruno
