Code:
while read i
  if id $i > /dev/null 2>&1
  then
    USER_LDAP_GROUPS="`id $i | cut -d\= -f4 | sed 's/([^()]*)//g;s/,/ /g'`"
    echo $USER_LDAP_GROUPS
  else
     echo "Invalid user $i"
  fi
done < txt1

Not only does that kludge not work for me but I don't understand why...it keeps saying "-bash: syntax error near unexpected token `done'". I believe the syntax is correct...there's a while followed by a done, I even put in a "do" just in case. The if statement is properly enclosed with fi...not sure why this is happening but I can't verify your suggestion.
