--show-client-cas does not show lots of entries

$ sslscan --no-colour --show-client-cas mail.mdv.de

  Acceptable client certificate CA names:
/C=de/O=Mitteldeutscher Verkehrsverbund/CN=MDV WebAccess Authority/emailAddress=post@mdv.de

Works perfectly for a single accepted client CA name. But here comes the problem:

sslscan --no-colour --show-client-cas bersy.perdata.de

No acceptable CA names for client certificates are displayed, even though openssl s_client lists 66 of them.

$ openssl s_client bersy.perdata.de:443 < /dev/null

65 client certificate CA subjects omitted for brevity

Would you please list all those names?
