The SAS library performs all requests to the LabKey Server under a given user account with all the proper security enforced on the server. User credentials are obtained from a separate location than the running SAS program so that SAS programs may be shared without compromising security.
As in the Rlabkey package, user credentials are read from a file in the user’s home directory, so as to keep those credentials out of SAS programs, which may be shared between users. Most Unix Internet tools already use the .netrc file, so the LabKey SAS library also uses that file.
