Remove one use of IDENT_USERNAME_MAX IDENT_USERNAME_MAX is the maximum length of the information returned by an ident server, per RFC 1413. Using it as the buffer size in peer authentication is inappropriate. It was done here because of the historical relationship between peer and ident authentication. To reduce confusion between the two authenticaton methods and disentangle their code, use a dynamically allocated buffer instead.
