This algorithm authenticates the user’s credentials against a specific catalog facility. The catalog is determined from the facility chosen, and is obtained from the config file Facilities.xml.
Example - log a user into the catalog.
# Attempts to authenticate the user against the ISIS catalog.
# When logging into the catalog the session class is returned.
# This can then be used throughout to perform other ICAT routines.
session = CatalogLogin(username='SECRET',password='SECRET',Facility="ISIS")
# View the session ID for this catalog session.
print "The session ID is: " + session.getPropertyValue("Session")
Output:
The session ID is: b931877c-3cfb-460e-9e88-ed4257020477
