I authenticated a web page.but when i tried to access it the password which i have given is not accepted.Kindly give me asolution for this.

Since you specify 'apache' in your subject, I'll take the guess that your tried to password protect some directory on your webserver with a .htaccess file (or directly in httpd.conf).

- Which kind of authentication did you use (Basid, Digest...) ?
- How did your create and where did you store the user (and possibly group) credentials ?
- Can you paste the content of your .htaccess file (or the relevant part of your httpd.conf)
- If you are using .htaccess and that you're not in charge of the global server configuration, are you sure the admin did not disabled password protection on your directory ?

Anyway, more info needed to help you out.

I am having a similar problem here. I want to have the password file somewhere that no user can read it but it only works when i have it set to 644. This way all users can read the file and I consider this as a security issue. So jitheshmurali, make sure your password file (that must be indicated in the .htaccess file) is set to 644.

I have my apache 2 installed under /usr/local/apache2. Everything from there down is owned by the apache user and apache group with the permissions set to 0 for others. For example:
Can you post any specific errors you were getting and what you did to set up authentication?
