SQL Server Permissions For Adding New Windows Logins

Hi,

I've just had a customer who could not add a new Windows Login to their NAV database, the error message was "You do not have the required SQL Server permissions to perform the current security activity". The user trying this already had the 'db_owner' and 'db_securityadmin' roles for the NAV database, and they also had the 'securityadmin' server role. I added the 'db_securityadmin' role for the master database but this made no difference. In the end I added 'db_owner' role for the master database and this solved the problem.

I can never remember having this problem before, and having to give so many SQL privileges to enable adding a new Windows Login. Has anybody else encountered this before? The only difference I can think of is this is our first customer using SQL 2008R2, though we have many on SQL 2008.

Setup :

NAV 2009SP1 Classic Client
SQL Server 2008R2
SQL Server Security : Windows Authentication Only

Thanks

Jonathan
