The KDC database stores the maximum and renewable maximum lifetimes on
a per-principal basis. This is arguably a bug in the design. The KDC
will take the smallest of all the involved lifetimes (client, server,
any the TGS-REQ ticket) as the lifetime of the issued ticket. You'll
have to change the lifetimes on the client principal and the TGT
principal, as well as on any service principal you wish to
[maybe this should be a FAQ...]
