Archived - Authentication issues when connecting to a Lion SMB server

This article has been archived and is no longer updated by Apple.

Symptoms

When attempting to connect to an SMB share hosted on Lion Server, the authentication dialog may reject the password unless the domain is included as part of the username, like ADS\user.

Resolution

OS X Lion v10.7.2 and later

After updating to OS X Lion v10.7.2 or later, prepending the domain/workgroup name to the username is no longer necessary.


OS X Lion v10.7 and 10.7.1

If Lion Server is bound to Active Directory, a member of Open Directory, or is configured for a different Microsoft Windows domain than the client, the authentication may not work with the correct username and password.

To resolve this, specify the domain/workgroup of Lion Server with the username in the authentication dialog. For Active Directory, use the first part of the domain name; for example, for ads.example.com, put ADS\ in front of the username.  For Open Directory, specify the first part of the DNS name of the server.  If connecting to a server with DNS name lion.example.com, put LION\ in front of the username.
