Hoss Man commented on SOLR-365:
-------------------------------

This is ... odd.  Solr isn't making any assumptions about the length of the user name.

Paul: what does the output of "who | grep psund " on your system print?

> to reproduce, create a user account that is more than 8 characters long.  Then try to do a command like snappuller and even though the config is setup properly, it attempts to do a sudo.  The reason is that  2 different methods are used to calculate the user, one of which truncates accounts to 8 characters.
> While user logins used to be limited to 8 characters, this may not be the case on modern UNIX.  
> Here is a snippet I get by adding the -x debug flag to bash.  Note how oldwhoami is a truncated version (psundlin) of the full login (psundling).
> + fixUser
> + [[ -z psundling ]]
> ++ whoami
> + [[ psundling != psundling ]]
> ++ who -m
> ++ cut '-d ' -f1
> ++ sed '-es/^.*!//'
> + oldwhoami=psundlin
> + [[ psundlin == '' ]]
