dn aliases?

Is there a way to create aliases for dn's?

For example, right now I point my client to:

rootdn: dc=my,dc=example,dc=com user: cn=Manager,dc=my,dc=example,dc=com org: ou=org,dc=my,dc=example,dc=com

Now, I want to create an alias so that the examples below point to those above:

rootdn: dc=my,dc=alias,dc=com user: cn=Manager,dc=my,dc=alias,dc=com org: ou=org,dc=my,dc=alias,dc=com

In other words, any reference in my client to: dc=my,dc=alias,dc=com would resolve in the ldap database to: dc=my,dc=example,dc=com

Is there a way to do this? If so, where can I locate these instructions?

Thanks!
