Hi 

Recently we did migration from moss 2007 to sharepoint 2010

Some users are getting access denied error

so do i need to upgrade moss 2007 ssp in order to carried over the current permissions to current sharepoint 2010 sites

Is there any pattern to the users who are getting login issues?

Have you changed your authentication method as part of the migration?

Have you confirmed that the users really do have permisssion to the items they are trying to access?

Claims Authentication

Users are syncng good but when i pick from people picker it is saying no exact match were found

In web application web.config file (where you are searching for people), add the following lines in <PeoplePickerWildCards> tag.

<clear />
<add key="AspNetSqlMembershipProvider" value="%" />
<add key="SqlMember" value="%"/>
<add key="SqlRole" value="%"/>

Hi,

Have you tried to remove user and add user again.

Other option could be run following command

STSADM o migrateuser oldlogin MYDOMAIN\eholz newlogin MYDOMAIN\eburrell ignoresidhistory

thx
