[Pkg-shadow-devel] Length of user names with regard to encoding.

[Marc Haber]

Hi,

adduser has been enforcing a 32 character limit for the _encoded_ user
name. Thus, ффффффффффффффффф (which is 34 bytes long in the encoded
variant) is invalid from adduser's point of view.  We are testing for
this in the test suite.

However, during debugging and improving UTF-8-support, I have found out
that an account named ффффффффффффффффф _CAN_ be created and seems to
happily work.

Should we:

- continue to enforce the encoded length of the user name to be < 32
- limit length of the user name to be < 32 _characters_ regardless
  of how long it is encoded?
- drop the length limit altogether?
- something else?

Greetings
Marc
