You have a partial install of it. You've probably only the binaries
neccessary to run it on your system. But not the header files to
compile applications which use mysql resp. libmysqlclient in our case.
Read on if you want mysql support. If you don't want to log to a mysql
db, then you don't need mysql. Leave it as it is in this case.

A _complete_ install of, for example, mysql consists not only of the
usual binary packe but additionaly of the mysql-dev package, which
contains .h files and similar stuff neccessary to compile and link
applications like linesrv against mysql. So if linesrv should use
mysql on your system, then the development files are needed also, not
only the libraries and programfiles of mysql.

This is not a special problem of linesrv... you need those things
always if you want to compile programs which use certain libraries.

linesrv can use libmysqlclient and libpam, so in "debian
testing" for example you need the following packages:
- libmysqlclient12
- libmysqlclient-dev
- libpam0g
- libpam0g-dev

btw: you don't need a full mysql installation, the mysqlclient
libraries should be sufficient.

Your passwordfile is probably /etc/shadow, as long as you aren't using
any cluster environment or other special things. 'cat /etc/shadow' or
'cat /etc/passwd' should reveal lines like

username:$1$YVtjnJW.$riTSCrO1BKKy9..MyU6v8.:12698:0:10000::::

If /etc/passwd has a line like "root:x:0:0:root:/root:/bin/bash" (the
x in the 2nd field is relevant) then your password file is
/etc/shadow, which is probably the case on your system.

crypt is part of glibc, which you probably have installed...
(no, you don't have to check that... you have it installed.)
Execute "/lib/libc.so.6", you will get something like:

If you're using crypt for user authentication, then you need
the following line in your linesrv.conf:
passwd_file /etc/shadow
For user authentication using PAM you don't need this line,
comment it out (default, as in
linesrv-2.1/server/config/complete_syntax/linesrv.conf).

Hope that helps you... seems you have to learn a lot... ;)
