Re: [keycloak-user] Email is unique within one realm

Unfortunately this would also not solve the original issue: we are handling these accounts like all other accounts and using standard Keycloak features which all bases on the email address. Would it be a smaller effort to handle this check on software level? You can configure the uniqueness of the email address in each realm, check this on software level and delete the unique index in the database. Would that be manageable?

“Email address unique or not?” – I have found a similar discussion and a recommendation in the OpenId-Connect-Spezification: “Therefore, the only guaranteed unique identifier for a given End-User is the combination of the iss Claim and the sub Claim. All other Claims carry no such guarantees across different issuers in terms of stability over time or uniqueness across users, and Issuers are permitted to apply local restrictions and policies. For instance, an Issuer MAY re-use an email Claim Value across different End-Users at different points in time, and the claimed email address for a given End-User MAY change over time. Therefore, other Claims such as email, phone_number, and preferred_username and MUST NOT be used as unique identifiers for the End-User. “ [OpenId-Connect Core Spzification 1.0 – 5.7 Calim Stability and Uniqueness] So, at this point, we have a local restriction of Keycloak which says that the email claim has to be unique. This is absolutely compliant but as the example exactly describes the email case, I think others were also dealing with this topic. Because of this, the spezification recommends to make the email address not unique. What do you think, would that be an option for a new feature? *From:* Stian Thorgersen [mailto:sthorger@redhat.com] *Sent:* Thursday, November 26, 2015 8:58 AM *To:* Sebastian Olscher *Cc:* keycloak-user(a)lists.jboss.org *Subject:* Re: [keycloak-user] Email is unique within one realm I meant that you'd use the attribute option only for the "server accounts" where it's not the email of the user, but a contact email. For regular users you'd continue using the email field. Would that work? You can even write a custom protocol mapper that takes either and adds it to the same claim in the token. The email field has a unique constraint in the database and that's not something we can enable/disable with a realm option. I think we'd have to add an additional field or store the email as an attribute. Could be a bit messy and quite a bit of work to do.

As I understood the reason why the email address was designed as unique is that it could be also used as the username. Would it be possible to implement this as a feature within the realm config? You can configure if you want to allow the usage of the email address as the username. If not, the email address has not to be unique. For us, this would make totally sense and helps us to fulfill the requirement. Would that be possible if there are no other preventing side effects? *From:* Stian Thorgersen [mailto:sthorger@redhat.com] *Sent:* Wednesday, November 25, 2015 8:31 PM *To:* Sebastian Olscher *Cc:* keycloak-user(a)lists.jboss.org *Subject:* Re: [keycloak-user] Email is unique within one realm In that case could you just set the contact email address as an attribute instead? The email field has to be unique has it can be in place of username. You could even use protocol mappers to map either email or the attribute to the same claim in the token.

These users may have the same responsible contact person as there is a system using this account and no real human. The contact person is identified by the email address. Our own specific information will be designed as user attributes. For example: Username: sys_customer1 Email address: sebastian.olscher(a)traveltainment.de (Email address of the contact person who is responsible for this user) User attribute: Key=customer, Value=customer1 Username: sys_customer2 Email address: sebastian.olscher(a)traveltainment.de (Email address of the contact person who is responsible for this user) User attribute: Key=customer, Value=customer2 *From:* Stian Thorgersen [mailto:sthorger@redhat.com] *Sent:* Wednesday, November 25, 2015 3:04 PM *To:* Sebastian Olscher *Cc:* keycloak-user(a)lists.jboss.org *Subject:* Re: [keycloak-user] Email is unique within one realm That's not possible at the moment. Out of curiosity why would you have two different accounts for the same person?

Is there a possibility to fulfill the requirement to have different user (different usernames) for different applications within one realm which were managed and used by the same person/entity? For example: Username: I_Am_An_Admin Email: user(a)traveltainment.de (gets roles for every client within the realm) Username: I_Am_A_Normal_User Email: user(a)traveltainment.de (get roles from only one client within the realm) Is this unambiguity of the email address configurable?
