Hi! Thanks for reporting this. The username validation uses the regular expression ^[a-zA-Z0-9]+((_|\.)?[a-zA-Z0-9])*$, which means usernames should contain only Latin letters and numbers, with optional _ or . symbols in between.

Absolutely no worries! I think we need to provide some error messages, as it can sometimes be unclear why this field is being selected, what the expected value should be, and so on :)

Is it possible to allow mail-adress as username. Especially when you want to use keycloak, this is important:

Details:

  Could not use specified `username`.  Violated one or more validation rules:

  • Value was -4 characters longer than the configured maximum length (16)

  • Value ('mail@xxxxxxxxxxx.net') did not match the configured regular expression (/^[a-zA-Z0-9]+((_|\.)?[a-zA-Z0-9])*$/)

Hi! I don't think it's a good idea to store an email in both the email and username fields, especially since the username is optional and can be left blank.

Instead, you can configure the following:

OIDC_EMAIL_ATTRIBUTE and OIDC_USERNAME_ATTRIBUTE - to use different fields for email and username.
Or set OIDC_IGNORE_USERNAME=true - to skip syncing the username.

Hope this helps!

Thanks a lot, it worked with:
OIDC_IGNORE_USERNAME=true - to skip syncing the username.
