new users are at least a three step process:
create the user in Active directory (you said that was done)
create a login for the user in SQL Server(you said that was done)
Create a user in the database to match the login(missing?)
Assign the appropriate permissions/role so the user can access data(missing)
--creat the login for the Active Directory User
CREATE LOGIN [mydomain\NewUse] FROM WINDOWS;
--switch to the right database: if more than one database, repeat for each one
--Create the user to match the login
CREATE USER [mydomain\NewUser] FROM LOGIN [mydomain\NewUser]
--put the user in the correct permissions role
exec sp_addrolemember 'RoleAlreadyCreated', 'mydomain\NewUser'
--an example in case you don't have the role with the right permissions yet:
CREATE ROLE [AlmostOwners]
EXEC sp_addrolemember N'db_ddladmin', N'AlmostOwners'
EXEC sp_addrolemember N'db_datareader', N'AlmostOwners'
EXEC sp_addrolemember N'db_datawriter', N'AlmostOwners'
--can the users EXECUTE procedures? comment out if false
GRANT EXECUTE TO [AlmostOwners]
exec sp_addrolemember 'AlmostOwners', ' mydomain\NewUser'
