Doc link authority issue

Running R5.11 on V5R1 AS/400.  Clients were coming up for recert the last 
6 months.  Initially I would receive word from client they needed to 
recertify their Notes id and I did recertify and that went OK.  I then 
started renewing as my cert log showed personnel were coming up and I 
assumed when the clients logged on their Notes id would update themselves 
automatically.  Since I had not received word they were having problems or 
daily notification of expiring ids I assumed all was well.  By experience 
the R5 environment is not automatically upgrading their ids as intended 
and allowing them still to function. 

Our app developers then created a performance appraisal application with a 
Notes interface and a web interface.  If a client uses the browser, a web 
link is transferred,  there is no problem as long as they have a valid 
username and Internet password.  If a Notes client is used a doc link is 
sent, and some of the  recepiants clicks on the link and  receive a "you 
are not authorized.." dialog box. 

Sometimes I have to send the initiator of the evals an upgraded userid if 
several recepiants have the same problem or if only one recepiant has the 
problem I send that person an upgraded userid and all is processed OK. 

(1) Since I have not been able to convince people to just use the web 
interface is there any way to identify the clients in my environment who 
do not have an updated Notes id on their client. 

(2) What confuses me is, if their userid at their desktop does not agree 
with the certificate information in the Domino Directory, why are doc 
links the only problem showing up and not the initial sign on to the 
system.
