Regarding issue with auxprop plugin

[Om Kale]

Hey Dan,
Thanks for the inputs. I have the sasldb folder (I presume sasldb library
is something different. If yes, where do I find this) inside the cyrus-sasl
installation folder. The contents of sasldb folder are as below:
/sasldb$ ls -lrt
total 176
-rw-rw-r-- 1 cisco cisco  4750 Jan 27  2012 sasldb.h
-rw-rw-r-- 1 cisco cisco  2527 Jan 27  2012 NTMakefile
-rw-rw-r-- 1 cisco cisco  2606 Jan 27  2012 Makefile.am
-rw-rw-r-- 1 cisco cisco  3882 Jan 27  2012 db_none.c

-rw-rw-r-- 1 cisco cisco  9366 Jan 27  2012 db_gdbm.c

-rw-rw-r-- 1 cisco cisco 14104 May  9 16:17 db_none.o
-rw-rw-r-- 1 cisco cisco 18533 May 18 14:12 Makefile
-rw-r--r-- 1 root  root  31336 May 18 14:12 allockey.lo

I have configured using
--with-dblib=BERKELEY as well..didn't give me any issues. Initially, I had
used '--with-dbpath=/etc/sasldb2', but later understood that this cannot be
used for MD5 auth.

However, 'pluginviewer -a' gives none.
dd17-ubuntu-okale:/usr/local/sbin$ pluginviewer -a
Installed and properly configured auxprop mechanisms are:
<none>


The ldd on pluginviewer looks like this:
dd17-ubuntu-okale:/usr/local/sbin$ ldd pluginviewer
linux-vdso.so.1 =>  (0x00007ffcc87e3000)
libsasl2.so.3 => /usr/local/lib/libsasl2.so.3 (0x00007f9f3a2e4000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f9f39f1a000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f9f39d16000)
/lib64/ld-linux-x86-64.so.2 (0x00007f9f3a501000)


The ldd on my memcached binary looks like this:
dd17-ubuntu-okale:~/Downloads/memcached-1.5.7$ ldd memcached
linux-vdso.so.1 =>  (0x00007ffd6bfb8000)
libevent-2.0.so.5 => /usr/lib/x86_64-linux-gnu/libevent-2.0.so.5
(0x00007f270c40e000)
libsasl2.so.3 => /usr/local/lib/libsasl2.so.3 (0x00007f270c1f1000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0
(0x00007f270bfd4000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f270bc0a000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f270ba06000)
/lib64/ld-linux-x86-64.so.2 (0x00007f270c654000)

So they are pointing to the same location.

For installation of cyrus, I have downloaded the tar.gz, untarred it and
then configured it using ./configure, followed by make, make install and
adding the symbolic link as mentioned in the documentation.
However, for the server side application (in my case memcached) using
cyrus-sasl, I don't see any generalized way, I only see documentation for
postfix server application.

Thanks and Regards,
