OK, so I found that my snmp commands actually did not find the MIBs, or more
precisely did not read /etc/snmp/snmp.conf, as I get the following whatever I
put in the said file:

MIB search path:
/home/daniel/.snmp/mibs:/usr/share/mibs/site:/usr/share/snmp/mibs:/usr/share/mibs/iana:/usr/share/mibs/ietf:/usr/share/mibs/netsnmp:/home/daniel/.snmp/mibs
Cannot find module (TCS-MIB.mib): At line 0 in (none)

even though I have
% ls -l /home/daniel/.snmp/mibs/TCS-MIB.mib ~
-rwxrwxr-x 1 daniel daniel 4548 20 juin 11:38
/home/daniel/.snmp/mibs/TCS-MIB.mib*
So I changed for a pass extension on which I a currently working. A basic
example that does not take my private mib structure into account works ONLY IF
I replace at the end of the module identity
::= { enterprises 16304 3665 }
which is the kind of thing I must have, with
::= { enterprises 16304 }
which is simpler but works even though it is not the expected structure
Thanks for any help,

So, nobody? Just in case this was not clear previously, the Net-SNMP that comes
with debian is v5.4.3, Synaptic says

Any idea why I cannot extend the agent using perl and why I cannot use the
access control0 stored in config file?
Daniel.

The way I created the new user (test1) is
% sudo net-snmp-config --create-snmpv3-user
then answering the questions. As I reinstalled (using synaptics) all
snmp-related packages after trying to compile the latest sources, this should
be the vendor-provided version.
The said line (createUser...) did not disappear from the file in /var neither.
But trying again with /usr/bin/net-snmp-config (dated 20120105) and another
user (test2) did not reproduce the problem (but the line for test1 is still
there).
The recommended usage for password is, from what I read, to put it in the
~/snmp.conf file (using a defAuthPassphrase, together with the adequate
defSecurityLevel, defAuthType and defPrivType) so that it does not appear in a
command's argument, which is safer.

Which snmpd binary are you running here?
The vendor-supplied one, or one that you've compiled yourself?
Try giving the full path to the binary, just to make sure.

It won't disappear from the /etc/snmp file, no.
The *only* config file that the agent re-writes is the one under /var.

Sorry - that's too vague to be clear as to what you're trying to do.
