Alon Bar-Lev commented on SSHD-584:
-----------------------------------
I do not understand, wikipedia is not good source for this information if valid
openssh environment is not working with apache-sshd. I pasted the code snip,
openssh only verify for group/others write, it does not matter how many members
group has.
> permisison of ~/.ssh/config with group/world readable is legal
