family_namelastName
nicknamenickname

Mapping Between JWT Token and ICM Account

External JWT Token to ICM Profile

The ICM server maps ID token claims to the user's profile data:

ClaimProfile Attribute
given_namefirstName
family_namelastName
nicknamenickname
emailemail
gendergender
birthdatebirthdate
phone_numberphoneNumber
login

Built using the pattern:

externalUserName + "#" + externalUserId + "@" + identityProviderId

with:

  • externalUserName: claim preferred_username fallback to unique_name fallback to name fallback to sub
  • externalUserId: claim sub or claim oid (in case of Microsoft Azure AD
  • identityProviderId: ID of the identity provider (see Concept - Single Sign-On (SSO))

The ICM supports JWT Token creation ("token" resource). These JWT are filled using the following data:

Profile AttributeClaim
