LDAP and local server password manager options
 

I have a need for a password manager for a system consisting of about 12 servers all running RHEL 5.1. Some of the accounts are managed by LDAP, but there are some other accounts that are local to their respective server as well. I've been trying to search for an existing piece of software that would integrate with both LDAP and linux account management as the backend. I haven't been able to find anything.

My current design now is a java GUI running on the LDAP server and when the admin selects and LDAP account to update the password it just executes a script using the command line tool ldappasswd. If they select a local account I would use ssh and run a local script using passwd.
In this setup how can I pass the userid of the local account to the remote script (There is more than one local account on some of the servers)?

Is there a better solution to this problem or something that already exists that handles this?

Thanks for the help.
