Unknown error being generated by openssl-0.9.8a

[Adam Ringel]

We are using the openssl-0.9.8a library in a program called lftp to use FTP over an SSL channel on a Solaris platform.  We are getting an unknown error when we try to connect to a FTPS server running SecureTransport 4.1.1

The triggering function is: SSL_connect
The results of a call to ERR_error_string return -
        error:00000000:lib(0):func(0):reason(0)

The only other information I have is that the result from ERR_GET_LIB() is not equal to ERR_LIB_SSL.
We negotiated the folowing parameters with the FTPS server before the error was obtained:
---> AUTH SSL
<--- 234 SSLv23/TLSv1
---> OPTS UTF8 ON

Does anybody have any idea of what error:00000000 signifies?
