If there are specific SAML users you want to manage in Shares instead of in SAML, you can add these SAML users to a local Shares group.
Note: You cannot add DS users to a local group.
Import SAML user.
Import the SAML group the user is a member of into Shares by logging in as a
user in that SAML group. A SAML group is automatically created when a user logs
in using SAML credentials. For more information on creating SAML groups, refer
to Creating SAML Groups.
Create new Shares group.
Navigate to Admin > Groups and select New. Give your group a name and select Create Group.
Add the imported SAML user.
Within your new group, select the Members tab, select the SAML user from the drop-down, then click the Add button.
