Oracle Calendar Server -- Multiple User Names and Migration

We were astounded to discover in customer data that it was possible to have non-unique user names in Oracle Calendar Server.

However, as the screenshots show, it was very easy for us in our test lab to create two "Jerry Garcia" users:

Despite the fact that I entered a valid password for only one of them I get the following screen on log-in asking me to select the one I mean (as though there's a way to tell them apart?)

This is bad enough -- but we then took the next step and invited them both to the same meeting.

Using the standard UNICPOUTU output this is the resulting data:

S 8780430

D 30

T Meeting with the two Jerrys

I 0

R N2

M Lennon John

W Lennon John

A TRUE 3 10

C [ .+] Garcia Jerry

C [ .-] Garcia Jerry

O

... making it impossible to tell which Jerry is which.

SO we've just added the capability to detect this in the USERS.TXT file before we get too far into a migration. If this situation arises, an error will pop up:
