Section 10.4.6. says:
o When the callback path is down, the server MUST NOT revoke the delegation if one of the following occurs: * (...) * The client has not issued a RENEW operation for some period of time after the server attempted to recall the delegation. This period of time MUST NOT be less than the value of the lease_time attribute.
It should say:
o When the callback path is down, the server MUST NOT revoke the delegation if one of the following occurs: * (...) * The client has not issued a RENEW operation for some period of time after the server attempted to recall the delegation. This period of time MUST be less than the value of the lease_time attribute.
Notes:
It does not make sense to revoke the delegation before lease_time period expiration and to not revoke it after.
