Symptoms

• Openssl will be used with OVD in some applications, however binds to OVD over SSL (mode 1; no authentication) fail with:
  
  
   openssl s_client -connect <OVD_HOSTNAME>:<OVD_SSL_PORT> -debug
  CONNECTED(00000003)
  
  <ENCRYPTED INFO>
  
  
  31132:error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake
  failure:s23_clnt.c:562:

•  

• OVD is configured to work on SSL mode 1 (ldaps -U 1)
  
  
  ldapbind -h <OVD_HOSTNAME> -p <OVD_SSL_PORT> -U 1
  bind successful
  
  And the access.log shows:
  
  
  [2008-09-23 02:18:33,482] conn=2 fd=0 slot=0 connection from <IP_ADDRESS> to <IP_ADDRESS> port <OVD_SSL_PORT> SSL
  [2008-09-23 02:18:33,572] conn=2 op=0 BIND dn="" method=0 version=3
  [2008-09-23 02:18:33,572] conn=2 op=0 RESULT err=0 tag=0 nentries=0 etime=0
• vde_start.sh includes, for example:
  
  
  exec "$VDE_DIR"/jre/bin/java -server -Xmx512m -Dvde.reconnInConnPool=true -Dvde.
  soTimeoutFrontend=120 -Dvde.soTimeoutBackend=120 -Djava.net.preferIPv4Stack=
  true -Dvde.home="<OVD_HOME>" -Dvde.lib="/<OVD_HOME>/server/lib" -Dvde.
  ldap.requireClientAuth="false" -Dvde.ldap.ciphers=SSL_DH_anon_WITH_DES_CBC_SHA,
  SSL_RSA_WITH_RC4_128_MD5,TLS_RSA_WITH_AES_128_CBC_SHA com.octetstring.vde.
  VDEServer > "$VDE_DIR"/log/vde_startup.log 2>&1
  
  Notice that the ciphers include SSL_DH_anon_WITH_DES_CBC_SHA
