Hi all,
Thanks for the information, but sadly still no luck. All I end up with is a shadow with a partial result that is in status fatal_error. I found this in the logs.
2017-05-16 15:40:04,072 [] [midPointScheduler_Worker-3] ERROR (com.evolveum.midpoint.model.impl.util.AbstractSearchIterativeResultHandler): Reconciliation of object shadow:7a70d0e8-839f-473b-ade6-ce38c91f7895(62f64fd8-4807-4a3c-8c32-129d8df890d1) from resource:94f21f3e-89b6-4d93-8cbc-e1bfc9fa41dd(External Database Userstore) failed: java.lang.StringIndexOutOfBoundsException: String index out of range: 1 expression in mapping 'JIT Username generation' in objectTemplate:52f4ca67-2bea-4da9-b26b-bffbd852fa39(JIT Username generation)(givenName=null; familyName=null; ) in expression in mapping 'JIT Username generation' in objectTemplate:52f4ca67-2bea-4da9-b26b-bffbd852fa39(JIT Username generation)
So givenName and familyName are passed as null to the objectTemplate, but I don’t know why null is passed as those attributes have values in the database. I’ve probably forgotten to configure something, but I don’t know what it could be.
Here is a part of the schema handling on the resource. I left out the attributes that have nothing to do with the username.

Hi Glenn,
the trick with object template from Roman and Gustav is one (probably best) possibility.
I can imagine also something like this (not tested, but should work):
<attribute>
<ref>icfs:name</ref>
<inbound>
<source>
<path>$account/accountUsername</path>
</source>
<source>
<path>$account/accountFirstname</path>
</source>
<source>
<path>$account/accountLastname</path>
</source>
<expression>
<script>
<code>
if (!basic.isEmpty(accountUsername)) {
return accountUsername // return accountUsername if it's not null
} else {
return accountFirstname + '.' + accountLastname // do whatever you need here
}
</code>
</script>
</expression>
<target>
<path>$user/name</path>
</target>
</inbound>
</attribute>
The mapping is inbound for icfs:name, because for normal connector, that attribute will always exist.
I don't know if you already have some inbound for that attribute, but you can have several (more than 1) inbounds for the same attribute.
The question is if the mapping should also change the existing username in midPoint, if not, the mapping should be weak.
Please note that this solution will not generate unique username in midPoint. For that you must use object template with iterators [1].

Subject: [midPoint] Generation of $user/name on reconcilitation of new account
Hi all,
We are creating a new environment in which midPoint will be used as IDM and WSO2 IS as IdP. When a user registers in the IdP (through Just In Time-provisioning with a federated IdP) this will be based on their eID. A username is not created, and thus not stored in the database userstore.
The next step is to add those users in midPoint. We planned on doing reconciliation during live synchronization. However, as the username is null in the database, we don’t have a value for the $user/name attribute and so the creation of the new user fails.
Is there a possibility in the schema handling to configure the first name and last name to generate a username? For example:
accountFirstName: Glenn
accountLastName: Boschmans
-> $user/name: gboschmans
I thought about using a Groovy script in the inbound of accountUsername to see if the attribute accountUsername is null. If not null return the value of the accountUsername attribute. If it is null, then I want to generate the username based on attributes accountFirstName and accountLastName. However, I’m not sure if it is possible to get the values of attributes accountFirstName and accountLastName.
Any ideas?
Thanks in advance!
Best regards,
Glenn Boschmans
