bash script to access directory paths from a text file

I have a text file that contains a list of folder names, one per line, that I want to access in a directory. I intend to use the script as follows:

main.sh folderlist.txt foldername/

Here is the code: 

#!/bin/bash
DIRFILE=$1;
INPUTBASEDIR=$2;
while read dir; do
    echo "$INPUTBASEDIR$dir"
    ls -l "$INPUTBASEDIR$dir"
done<"$DIRFILE"

When echoing the concatenated path, it outputs the correct and existing path. However, the ls line spits out : No such file or directory. What must I do to have the second line properly output the files under that directory?

One cannot be sure it is "correct and existing path". Command echo simply outputs the argument string. Whether the file/directory exists or not does not matter.

Only ls looks for the file. So it appears to me that there are some entries in folderlist.txt which are not in foldername.
