openssh unix dev - Dec 2010 - Problem of updating openssh-4.4p1 to openssh-5.5p1 with MAX_ALLOW_USERS option

Hello!

We have the server with RHEL 5.5 (64-bit) and need to connect many parallel
users over ssh (OpenSSH).
Usually we use openssh-4.4p1, builded from the sources with changed
"servconf.h" file by this type:
 ???#define MAX_ALLOW_USERS ????????10000 ????/* Max # users on allow list. */
 ???#define MAX_DENY_USERS ???????????10000 ????/* Max # users on deny list. */
 ???#define MAX_ALLOW_GROUPS ?????10000 ????/* Max # groups on allow list. */
 ???#define MAX_DENY_GROUPS ????????10000 ????/* Max # groups on deny list. */

and configured with this additional options:
# ./configure --prefix=/usr --sysconfdir=/etc/ssh --with-ipv4-default --with-pam
--without-4in6 --without-zlib-version-check
# make
# make install.

After compiling and restarting service ssh (# service sshd condrestart) we had
possibility to connect many parallel users to our server.

Now we want to update a version of OpenSSH from openssh-4.4p1 to openssh-5.5p1
but have a problem with the maximum quantity of line "AllowUsers" in
file "/etc/ssh/sshd_config" after such operations as we had done with
openssh-4.4p1.
# service sshd restart
Stopping sshd:
?????????????????????????????????????????????????????????????????????????????????????????????????????[FAILED]
Starting sshd: /etc/ssh/sshd_config line 622: too many allow users.
?????????????[FAILED]

What we do incorrect?

Thanks.

With the best regards, Alex.

Those definitions don't do what you think they do. They are the number
of users that can appear in AllowUsers/DenyUsers/AllowGroups/DenyGroups
statement and have no effect on the number of users that are allowed to
concurrently log in.
