Apparently nothing that hits port 636 has any details recorded.  Why 
anything would be hitting the LDAP server, which isn't even running, is 
beyond me.  I now have two two users showing up every two seconds for 
failed signon attempts--while their 5250 sessions are up, running and 
logged in!   Neither of the two is configured to use Kerberos in Ops 
Navigator or the 5250 session.

Yep, I can see the entries every two seconds.

> 20 PWRADR Remote address
Completely blank whenever the remote port is 636.

Two Ps, followed by thousands of Qs, that all makes sense.

>40 PWJOB Name of job
QTVDEVICE, but its joblog has no further info.....

> 50 PWUSER Name of user
QTCP, no help there......

>60 PWNBR Number of job
Used with PWJOB above to look at a non-useful joblog...

> 70 PWPGM Name of program
QCMD, no help there....

> 80 PWUSPF User profile
QTCP, no help there....

> 90 PWRPORT Remote port
All to port 636.....

> 100 PWDEVN Device name
Completely blank for port 636 entries.....

I've gone field by field through the entire output of CPYAUDJRNE and 
nothing helps for the entires where the port=636.  Everything is either 
blank or leads to a job log with no details.   I guess we'll move the box 
with ETHEREAL to the switch with the iSeries.  Traffic on port 636 should 
stand out like a sore thumb.
