If your ODBC Driver uses SSL encryption or extended password encryption to pass the password to Adaptive Server, you need to set the $SYBASE and $SYBCSI_PROVIDER_DIRECTORY environment variables.
Set the $SYBASE environment variable to the Sybase installation directory and the $SYBCSI_PROVIDER_DIRECTORY environment variable to a directory with suitable cryptographic providers. Typically, $SYBCSI_PROVIDER_DIRECTORY is set to $SYBASE/DataAccess/ODBC/lib/csi, unless you have defined $SYBCSI_PROVIDER_DIRECTORY to point to the location of a different but compatible provider.
