397-401: Change totakeBufferis appropriate.The switch from
takeSmallBuffertotakeBufferallows the buffer to accommodate longer inputs, aligning with the PR objectives to fix authentication errors due to long usernames or passwords.However, verify the
takeBufferimplementation to ensure it handles dynamic buffer growth as expected.Verification successful
Change to
takeBufferis verified.The
takeBufferfunction inbuffer.gohandles buffer allocation with necessary checks, supporting the change inpackets.gofor better handling of larger inputs. This aligns with the PR objectives.

Description
Targets issue in #1482. When username/password (JWT token usually) are too long, there are unable to fit into buffer, which has only 4k at connection startup. Using takeBuffer (which autogrows) instead of takeSmallBuffer should work in this case.
I did not find any "better" solution to this problem as checking length of packet before choosing buffer would be practicaly the same logic and conditions, what takeBuffer does. If there is need to use takeSmallBuffer for perfomrance reasons, there can be takeSmallBuffer kept and takeBuffer called only after failure, which seems to be ugliest solution.
