Is KRB5CCNAME exported?

Try:

parallel echo '${}' ::: KRB5CCNAME
export KRB5CCNAME
parallel echo '${}' ::: KRB5CCNAME
seq 10 | parallel --sshlogin :,$SERVER --load 75% echo

If KRB5CCNAME is needed for ssh, then if it is not exported that would
explain all you see.

Variables transferred using env_parallel are not set when ssh starts.
They are being set on the remote system after ssh has logged in, so if
ssh needs some variables they will have to be exported.
