Unfortunately credentialIDs in u2f are 255 bytes long which with base32 encoding becomes 408 bytes. The default size of a xorm string field is only a VARCHAR(255) This problem is not apparent on SQLite because strings get mapped to TEXT there. Fix #18727 Signed-off-by: Andrew Thornton <art27@cantab.net>
