Much ado about logins and SIDs
Some time back I posted about Logins and SIDs and I’ve had a number of people ask me for examples. So I’ve updated the post here.
A very common issue that’s raised in the newsgroups relates to SQL Server logins that need to be moved between servers. When you recreate a SQL Server login (ie: not a Windows one), by default you get a new security ID (SID), even though you have the same user name and password.
