Maximum SASL2 Password Length?

[Forrest Aldrich]

I'm trying to determine what the max length is for SASL2 passwords....
Looking through /usr/local/include/sasl/sasl.h, I see references to:
   typedef int sasl_server_userdb_checkpass_t(sasl_conn_t *conn,
                          void *context,
                          const char *user,
                          const char *pass,
                          unsigned passlen,               
                          struct propctx *propctx);

   /* Plain text password structure.
    *  len is the length of the password, data is the text.
    */
   typedef struct sasl_secret {
       unsigned long len;
       unsigned char data[1];              /* variable sized */
   } sasl_secret_t;

Can someone clarify?   I need this for a database service (ie: to know 
what field limits to use).

Thanks.
