Yes you will have all the GRANTS for every user sitting in the 'mysql' schema
(from mysq.user) if you use the --all-databases option of mysqldump.
Here is something radical if you want to record the grants yourself:
Run the following query
SELECT CONCAT('SHOW GRANTS FOR ''',user,'''@''',host,''';') UserGrants
FROM mysql.user WHERE user IS NOT NULL AND user <> '' AND host IS NOT NULL AND
host <> '';
This query will create a SHOW GRANTS FOR command for all users in the mysqld
instance. Pipe the output to a ShowGrants.sql file
Mysql --skip-column-names -h<host> -u<username> -p<password> -A -e"SELECT
CONCAT('SHOW GRANTS FOR ''',user,'''@''',host,''';') UserGrants FROM mysql.user
WHERE user IS NOT NULL AND user <> '' AND host IS NOT NULL AND host <> ''" >
ShowGrants.sql
Then execute the script:
Mysql -h<host> -u<username> -p<password> -A < ShowGrants.sql > AllGrants.sql
AllGrants.sql will have all GRANTS but each line has no semicolon at the end
Just append a semicolon at the end of every line like this:
sed -i 's/$/;/' AllGrants.sql
Give it a try !!!

Here is a follow-up question: Using mysqldump, I'm about to dump all
databases and import to another instance - new . My question is do I
need to define all security and users in the new mysql or the security
definitions and privileges will be included in the dump file created by
mysqldump.
Please help me!

did you export/import your data, or just copied the data files from your
old
to the new MySQL?
did you reload privileges after changes?
FLUSH PRIVILEGES;
