Minium Permissions necessary to create a login?

What are the minimum permissions necessary to use CREATE LOGIN?

I'm using db_accessAdmin and db_securityAdmin and db_owner. The user as access to the database.

It still says I can't create the login. What am I missing?

The answer is in Books Online:

http://msdn2.microsoft.com/en-us/library/ms189751.aspx

"Requires ALTER ANY LOGIN permission on the server. If the CREDENTIAL option is used, also requires ALTER ANY CREDENTIAL permission on the server."

Creating a login requires permissions at the server level, it cannot be accomplished with database level permissions.

Thanks
