Hi all,
everything I has done before with ssl worked out of a box (telnet with
ssl, https-pages viewed with Netscape, imaps with Messenger). But now I
have a client program using the c-client library which is capable of ssl
by openssl.
Using the mtest program of c-client to connect via imaps to my
mailserver at university I get
> %unable to get local issuer certificate:
>/C=DE/ST=Baden-Wuerttemberg/L=Ulm/O=Universitaet
> Ulm/OU=Universitaetsrechenzentrum/CN=imap.rz.uni-ulm.de
> ?Can't establish SSL session to imap.rz.uni-ulm.de/imaps,993
After many hours searching and the output of 'openssl c_client -connect
imap.rz.uni-ulm.de:993'

I am sure the error is the missing trusted certificate of
"/C=ZA/ST=Western Cape/L=Cape Town/O=Thawte Consulting
cc/OU=Certification Services Division/CN=Thawte Server
[EMAIL PROTECTED]".
But how/where can I obtain it and how has it to be integrated. I
searched over 3 hours and haven't found any information about. And if
this is not possible, how can I start SSL secured connections to my
university server without it.
Thanks in advance, Juergen
