Hi,

i'm using Bacula 7.0.5 with TLS setup for all connections. The
certificates are using the FQDN of the participating nodes as the
common name. Everything works for a normal setup consisting of a
director, a storage daemon and file daemons on different hosts with
both IPv4 and IPv6.
If i use the option SD Calls Client = yes in the director's Client
resource for a specific client, then the TLS negotiation for this
client will fail.
The error message is

bacula-fd Fatal error: bnet.c:278 TLS host certificate verification
failed. Host name "[<IPv6 Address of the storage daemon>]" did not
match presented certificate

This error occurs for all clients with SD Calls Client = yes. It seems
the storage daemon does not send its FQDN during the TLS handshake.
For all other TLS handshakes the FQDN is sent as expected.

Do i miss something here, or is this a bug?

Btw., when using SD Calls Client, the file daemon should also allow
TLS Verify Peer and TLS Allowed CN, as it is now acting as a server
role, shouldn't it?

Regards,
Sascha
