@dupree972 can you give more info? Is this on a fresh install? Are you using any other auth methods?

[engelgabriel]

@rodrigok this looks like an errors on the LDAP sync function, can you please take a quick look?

[mpetersen42]

This is on an existing upgraded install using only LDAP (and local) authentication. If you "pre-create" a local user with the same username they'll be converted to LDAP on login fine. However if you login as an LDAP user that doesn't exist it attempts to create the user with an undefined username.

@mpetersen42 Which field are you using as your LDAP Username Field?

[mpetersen42]

Blank or default, so 'sAMAccountName'
