The focus of GUMS version 1.3 has been to provide an OSG OpenSAML-XACML AuthZ interface to allow for interoperability with other grid components, the ability to store the configuration in a persistence factory so that it can be shared between multiple gums servers, the ability to merge a configuration template from a URL, and the ability to ban users or VOs (which can be added manually or read from a file). Several other features have also been added:
A new table for storing the configuration has been added. Also, an email column has been added to the USER table.
GUMS 1.3 server can read configuration formats 1.1, 1.2, and 1.3, but a previous version of GUMS cannot read a later version of the configuration. New in the 1.3 configuration format is additional fields in all the LDAP classes, two global options to disallow gridmap file creation and banned user groups, and the ability to configure a persistenceFactory element to store the configuration within it for clustered GUMS servers.
