Subject:   Canto Cumulus under Linux emulation

Canto Cumulus (http://www.canto.com) is a well-known media management 
database program that runs under many platforms including Linux.

I am trying to run the Linux version under FreeBSD 4.2.

I have no problem getting the Cumulus server program to launch and 
stay running under Linux. When I tried to login from the Cumulus 
client program (a different computer), Cumulus complained it didn't 
know me.

I learned that Linux keeps passwords stored in /etc/shadow but 
FreeBSD uses /etc/master.passwd. When I created a properly formatted 
/etc/shadow, I was able to login.

I have a feeling this means that Cumulus is bypassing Linux system 
calls for authentication and manually looking for the /etc/shadow 
file which is not implemented under the /compat/linux tree.
Does this sound accurate?

The next step is for me to have Cumulus create a database, but 
Cumulus complains when I give it a path inside my Linux account. I 
know that /home is just a link to /usr/home, so I tried the full 
link, and I also tried moving my account under the /compat/linux tree 
but that doesn't help.

I tried a kernel trace of the various Cumulus processes and can see 
the communication between the client and Cumulus but it is gibberish.

I am assuming Cumulus wants create a file on disk in the path I 
specify but for some reason is getting throwing off by the underlying 
emulation, for example, by looking for some other file it shouldn't 
be. However, the cryptic error message appears to be inside its 
"oSecureU.cpp." file.

I am trying to get help from the company's tech support, but they 
don't officially support FreeBSD.

Does anyone have any ideas?
