| SAML Authentication | Kevin Bui (lead developer) | Michelle Morris (University of Pittsburgh Mike Mendis | i2b2 now includes support for SAML-based enterprise authentication via an institutional Identity Provider. See more information below. | Michael Horvath | This change is meant to allow user params to take precedence over hive params. Currently, it's the other way around.
LDAP UPN Support | Michael Horvath | Active Directory enables other methods of binding which are more flexible besides just using the distinguished name. https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-adts/6a5891b8-928e-4b75-a4a5-0e3b77eaca52. This change is to enable binding the the User Principle Name form, which is very convenient when the distinguished names for users is not easily available (OU by department, etc.). | API to get all children of an ontology node | Kevin BuiThe metadata GetChildren API call, which returns information on the children of an ontology node, can now be configured to return multiple levels of children (e.g., children, children's children, etc.). This is done by specifying the numLevel parameters. By default, the function assumes numLevel = 1 and will return the direct descendants of the concept, which is one level of children. When the numLevel = -1 the function will return ALL descendants of the concept, otherwise the function will return up to and including the number of levels specified by numLevel (eg. numlevel=2 returns two levels of descendants, numLevel=4 returns four levels of descendants). |
