Problem with Authentication in sharepoint using active directory

I am currently using windows server 2008 machine. I have active directory and sharepoint setup on the machine. I have a user 'A' in the active directory and i have given the user read permissions to my site.

The problem i now face is that, if i log in as u开发者_如何学JAVAser 'A' the site simply shows "error:access denied". This problem goes away if i put 'A' as a site collection administrator, however that is not what i want. I just want 'A' to be a visitor that can browse the site. I also tried granting 'read' permission to my site for 'A' but that still gives me the access denied message.

Thank you for your time.

thats the cause of the problem your page library has got disintegrated from inherited permission from its parent site. you have to go to the page library settings and either add the user their as a viewer or start permission inheritance in the page library :)
