====== rdesktop w/keychain ======

The purpose of this script is to securely (fairly) login to multiple remote desktop sessions at the same time, while using passwords stored in OS X's Keychain facility.

Passwords can be stored as generic password types, the biggest caveat is that the format domain\username cannot be easily used.  Username@domain can however, so store your account information in that format.

Once passwords are loaded into Keychain, they can be retrieved in command line scripts via the security command.  For example:
<code>
security 2>&1 >&- find-generic-password -l $username -g CUIT.keychain
security 2>/dev/null find-generic-password -l $username -g CUIT.keychain|grep acct |cut -f 4 -d \"
</code>

The first gets the password for the keychain element with the name $username, and the second gets the account stored in the same one.

The rest of the script just runs through command line arguments and runs the rdesktop command with each host.  It's fairly straight forward.

The nice thing is that it can be aliased in your .profile to various account names.  E.g.: alias rda1.sh='rd.sh acct1@blah.domain'

Here's the script:
<code>
#!/bin/bash

if [ -z $BASH_ARGC ]; 
	then echo "Usage: $0 username (domain\username, username@domain) remote_host1 [ remote_host2 remote_host3 ... ]";
	exit 0;
fi

username=$1
#Get a password
passline=$(security 2>&1 >&- find-generic-password -l $username -g CUIT.keychain)
pass=$(echo $passline|grep -e ^password:)

#If the last command was NOT successful (security outputs the password as stderr!)
#then get the password via a cut and the account name via a grep and cut
if (( $? ))
	then 
		echo $passline  #if we're here, then "password" wasn't in the string, so there's a problem...
		exit 1 
	else
		pass=$(echo $pass|cut -f 2 -d \")
		user=$(security 2>/dev/null find-generic-password -l $username -g CUIT.keychain|grep acct |cut -f 4 -d \")

fi

echo "Establishing connections..."

#Fill arrays with values
j=0
for (( i=(( $# - 2 ));i >= 0; i--));
do
	hostlist[$j]="$(echo ${BASH_ARGV[$j]})"
	#echo ${hostlist[$j]}
	myarray[$j]="${BASH_ARGV[$j]} $i"
	#echo ${myarray[$j]}
	myarray2[$j]="${BASH_ARGV[$j]}"
	#echo ${myarray2[$j]}
	j=$(( $j+1 ));
done

for (( i=(( $# - 2 ));i >= 0; i--));
do
      echo ${myarray2[$i]}" ";rdesktop -k en-us -z -a 16 -g 1300x720 -r clipboard:CLIPBOARD -u $user -p $pass -T "${myarray[$i]}" ${myarray2[$i]} &

exit 0;
