Which part of the project does this feature apply to?

Backend

What would you like?

Currently username maxLength is 16. I would suggest to increase maxLength to 256.

Why is this needed?

We are using OIDC and so we use personal name from our IAM. Many users with firstname.lastname have a lenght more than 16. (e.g the the third most common german name andreas.schneider is already length 17)

Hey! We recently increased the username length limit to 32 characters for accounts created via OIDC. Do you think that still won't be enough? I'm a bit worried that allowing something like 256 characters would be unusable in the UI - both when displaying usernames and when mentioning users. But of course, it's open for discussion and we should figure out the best approach.

Won't be enough for long-ish double firstname + double lastname combinations. I have a coworker with such a combination that sums up to 39 chars

How about 64?

Yep, I will test how it looks in the UI 👌

Increased to 64 chars at the model level (e.g., when created via OIDC) and to 32 chars when set via the UI.
