I'm not sure if any of this is necessary:
if(sshConnection->useKerberos() && sshConnection->get_kerberosDelegation())
{
krbFwString="KRB5CCNAME=`echo $KRB5CCNAME |sed 's/FILE://g'` \
KRBFL=$HOME/.x2go/C-"+resumingSession.sessionId+"/krb5cc ;\
cp -a $KRB5CCNAME $KRBFL;KRB5CCNAME=$KRBFL ";
}
I believe that SSH will handle the delegation of GSSAPI/Kerberos credentials.
In my case, I'm using the modern keyring credentials cache:
KRB5CCNAME=KEYRING:persistent:22603
so I get:
cp: cannot stat âKEYRING:persistent:22603:22603â: No such file or directory
however my credentials are present on the remote machine and I can get to them
if I unset KRB5CCNAME.
