    perl script not able to make a connection with mysql

    I am trying to setup a squid logfile analysis tool, 'squidalyser'/. It has a perl script, that makes enries into a mysql database. I have made a user squidalyser, with appropoiate permissions and password, and also created the required database, as was instructed in the readme file. when i execute the file, which connects to the database, it gives me the error:
    Running ./ at Sun Sep 12 23:47:11 2004

    DB Name: squid
    DB Host: localhost
    DB User: squidalyser
    Squidlog: /var/log/squid/access.log
    DBI connect('squid:localhost','squidalyser',...) failed: Access denied for user: 'squidalyser@localhost' (Using password: YES) at ./ line 148
    Access denied for user: 'squidalyser@localhost' (Using password: YES) at ./ line 148.
    what could b this problem?
    Thanks in advance...

    one more thing

    I forgot to mention one more thing....
    when i manually connect to the database, i get connectd...i.e.
    [swaroop@localhost squidparse]$ mysql squid -u squidalyser -p
    Enter password:
    Reading table information for completion of table and column names

    Do you at any point have to put in the password?
