[stunnel-users] Problems with cert

Hello,  we  were  using  Stunnel  4.25  for  a  long  time without any

We used "verify=3". Our client config file:

service = stunnel-client
cert = client.pem
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1
verify = 3
CApath = certificates
CAfile = CAcert.pem
client = yes
accept = 3398
connect = XX.XX.XX.XX:3398

But  after  switching  to  Stunnel  4.34 (preserving configuration) we
started to get errors:

2010.11.25 13:13:30 LOG5[8332:5336]: Service rdp-database accepted connection from

2010.11.25 13:13:30 LOG5[8332:5336]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket

Main error is:
CERT: Certificate not found in local repository

Looks  like  stunnel  cannot  find  the hashed server's certificate in
C:\Program Files\stunnel\certificates (CApath = certificates)

We  tried  specifying  full  paths, but it does not help. Switching to
"verify=2"  (do  not  check server's cert) works ok. Also stunnel 4.25
(with verify=3) works ok on this configuration.

Could you help?
