However, when I look at the leases file or try to look for a lease object with the client's IP in omshell, the lease for that IP is not there. For what it's worth, leases given to clients from pool declarations are present. Should I be looking elsewhere, or is the dhcpd log the only place I can check to see if a client has requested a lease and given a fixed-address?
As Greg says, for fixed-address clients, no lease is stored. If you need to see a lease for it, then you may find reserved leases a viable alternative. These are normal dynamic leases, except that by adding the "reserved" keyword to the lease (AFAIK you can either edit the leases file or use OMAPI/OMSHELL) it is reserved exclusively for the one client. In other words, a reserved lease will never be reallocated even if it's long since expired.
