8604.0. "Urgent: special requirements for POP3" by NETRIX::"manuel garrido @sqo" (Manuel Garrido) Mon Jan 27 1997 15:15

Hi,

 Refering the same customer mentioned in topic no. 8389, the
100.000 user accounts issue is not the only one.

 We need *urgently* a POP3 able to support these mandatory features:
- 100.000 different user mailboxes.
- Enhanced security (APOP and C2 ?).
- UIDL: to avoid removing messages from unix mailbox.

  The "popd" that we are testing is the one which comes with
Digital Unix 4.0B, but does not support UIDL nor APOP.
  The Qualcomm popper is based on the unix user accounts, so the 65k
max. account number is limiting it.
  Is C2 going to support 100.000 different user accounts ?.
If so, is there a path available just now ?, where ?.

  Any suggestions are wellcome.
  Thanks in advance.

-- Manuel Garrido.

This is not the proper forum for URGENT problems or requests.  If you have
an URGENT problem you should escalate an IPMT case.  For an URGENT request,
you can contact Digital UNIX product management, but you have to realize that
Digital UNIX has a LONG development cycle, so if you request functionality
now, it may be available a year from now, or it may not.

POP is not developed as part of Digital UNIX, it is merely ported to work on
it.  It appears that the version distributed with V4.0 wasn't properly
ported, or it would at least support Enhanced Security.  You could try 
entering an IPMT against POP because it doesn't support Enhanced Security, 
but I think  you'll find that currently it is being supplied "as is" as a 
convenience to our customers, but it is not actively supported.  I also 
doubt you are going to be able to find a version of POP that works with 
100000 users on Digital UNIX before Digital UNIX works with 100000 users.  

Enhanced Security is an integral part of the Digital UNIX operating system, 
so of course the number of user accounts supported by Enhanced Security will 
be the same as the number of accounts supported by Base security.

I don't know your level of experience, but you could always try obtaining
the source for a version of POP from somewhere (I believe that Qualcomm's
version is public domain), and modifying it yourself to do what you URGENTly
need.  You're much more likely to be successful doing that than you are
entering an URGENT message in this notes file.

8604.2Some information and Thanks.NETRIX::"[email protected]"Manuel GarridoFri Jan 31 1997 04:3213
Sorry about the "urgent" header.
And thank you for your helpful explanations (I am new at DEC).
To whom may interest:
- There already exists a beta-patch for 100.000 accounts for Digital Unix 4.0
(to
be released about March-April).
- Although, a popper we have tried (from Washington) seems to work fine
having duplicated UIDs, in order to reach the 100.000 accounts.
- The Qualcomm popper is ported to our C2 security environment, and includes
UIDL function to preserve messages in the server.
- The IMAP4 from Washington seems to be ported to our C2 too.
Bye.

When I asked why other shells (e.g. bash) weren't thrown in with Digital UNIX, 
7581.1 said:

> There's another reason: if it's part of the operating system, we support it
> (yes, even if it's something freely available like EMACS).

This doesn't match with the above statement from .1.

Re .3

You'll notice in .1 that I wrote "I think you'll find" not "I know".  I wrote 
it that way for a reason.  I think (again, I'm not 100% sure) that there is
not
an official policy to support all applications that are ported to and released
with Digital UNIX, especially those on the layered product CD.  I suspect
that each group, or even each person has their own policy and that some will
fix some bugs and others won't.

I know that I personally have tried to convince some of the people responsible

for porting some of these applications to make changes that I consider to be
bug fixes and I was refused in at least one case.

This is not what you think it is. This patch was an experimental patch
for a specific customer that needed a large UID space (i.e. they wanted
to use employee badge numbers as UIDs) and NOT a large number
of UIDs themselved (i.e. no where near 100K accounts). 

I think there are several scalability issues that still need to be 
resolved before 100K accounts are practical. Specifically, I thought
the base system hashed password database had problems when scaling
up this high. C2 security systems also have problems. 

The point is that there is a  scalability project to address issues like this
but it's not  the same thing as the large UID support. That's just
one aspect of scalability.
