ContactFirstNameException error in the console. This error message appears when the first name is left out if importing a user from an LDAP server.Resolution
This behavior is intended for Liferay Portal. Liferay Portal requires the attribute of First Name for a new user to be created. This can be observed when creating a new user in the Control Panel. If the first name is left out, the user will not be created and the user will be reminded that the first Name is required. When importing a user from LDAP, this behavior is consistent in that if the user does not not have a first name in the LDAP configuration, Liferay Portal will not import or add the user and the exception will be thrown.
Currently in the portal.properties file, there is the option to ignore the last name attribute.
#
# Set this to true if you want the last name to be required when creating
# users.
#
users.last.name.required=false
Additional Information
There is a a request for our engineers to look into adding a property that allows for ignoring a missing first name attribute on LPS-45941.
