what privileged accounts exist on solaris

Hi Buddys,

We are using SUN-ONE LDAP and We need to define and implement a quarterly review of privileged accounts in the Unix environment.So, in the unix world, this would involve knowing what accounts are on each server, who has root access, what privileged accounts exist, who can sudo to these accounts etc.and how we can automate this process so that a manual exercise does not have to be performed on a regular basis.

Requsting you if anybudy help could me to get the mentioned information.
Any script or LDAP command ????

Thanks in advance.
