Is there any update on the compatibility issues between openssl-0.9.8n and openssl-1.0.0? The same configuration file was used in both cases. Linux CentOS 5.4 and SuSE 11.1. Stunnel and openssl both built from sources. I have a number of self-signed certificates in a sub-directory. With openssl-1.0.0, the error is: VERIFY ERROR: depth=0, error= self signed certificate:... SSL_accept: 140890B2: error:140890B2:SSL routines:SSL3_GET_CLIENT_CERTIFICATE:no certificate returned With openssl-0.9.8n VERIFY OK: depth=0, ... I have compiled and linked a version of openssh-5.4p1 from sources with openssl-1.0.0 and it works correctly. Carter -- Carter Browne CBCS cbrowne@cbcs-usa.com 781-721-2890
