<div class="moz-cite-prefix">Hi,<br>
<br>
this means that some of your LDAP user record doesn't have the
attribute, which you mapped as "Username LDAP Attribute" in the
admin console. For example if you configured <br>
"Username LDAP Attribute" as "cn" and some of your LDAP user
doesn't have "cn" . I've created JIRA
<a class="moz-txt-link-freetext" href="https://issues.jboss.org/browse/KEYCLOAK-1728">https://issues.jboss.org/browse/KEYCLOAK-1728</a> and have a fix,
which will be available in 1.5 . The fix will give you better
error message and won't break whole sync process with NPE, but
just won't import the incorrect user, which has missing attribute.<br>
<br>
Until that, you can either fix LDAP user records in your LDAP
server to contain the missing attribute, or you can configure
"Username LDAP Attribute" to different value. <br>
