VariableLDAP_USERNAME_ATTRIBUTE
Introduced Version1.6.10
DescriptionLDAP_USERNAME_ATTRIBUTE Environment Variable

This allows administrators to choose some attribute in the LDAP user record as the username in Humio. Normally, Humio will default to an email address, but in your LDAP you may have assigned user IDs and for uniformity in your organization it's desirable to use those rather than the email address. This option allows for that case.
