Description

Hello.

I would like to propose a new syntax of substring LDAP user DN.

For now, "DefaultLdapRealm" supports only "{0}" token to substitute user DN template with a user's principal.

In my case, I need to substitute user DN template with a part of user's principle.
For example if I have a principal as a form of 'organization code + username', I need to make the user's DN as follows:

CN=OAalice, OU=OA, ...

So I would like to propose a new syntax like "{0:beginIndex:endIndex}" in order to get a part of a user's principle. The template would be:

CN={0},OU={0:0:2},...

(The indexes are following Java's substring API's specifications.)

What do you think about my proposal? If you think it is acceptable, I would be able to make a fix.

Thanks.
