Also I see pluginviewer looks in the same directory for the plugins:
open("/usr/lib/sasl2/libotp.so.3", O_RDONLY|O_CLOEXEC) = 4
read(4,
"\177ELF\2\1\1\0\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0P\331\0\0\0\0\0\0"..., 832)
= 832
fstat(4, {st_mode=S_IFREG|0755, st_size=218776, ...}) = 0
mmap(NULL, 2204424, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 4, 0) =
0x7f33d9d44000
mprotect(0x7f33d9d59000, 2097152, PROT_NONE) = 0
mmap(0x7f33d9f59000, 24576, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 4, 0x15000) = 0x7f33d9f59000
close(4) = 0
mprotect(0x7f33d9f59000, 4096, PROT_READ) = 0
open("/usr/lib/sasl2/libdigestmd5.la", O_RDONLY) = 4
close(4) = 0
open("/usr/lib/sasl2/libplain.la", O_RDONLY) = 4
fstat(4, {st_mode=S_IFREG|0755, st_size=668, ...}) = 0
read(4, "# libplain.la - a libtool librar"..., 4096) = 668
close(4) = 0
open("/usr/lib/sasl2/libplain.so.3", O_RDONLY|O_CLOEXEC) = 4
I had changed the symbolic links as mentioned in the cyrus wiki like this:
ln -s /usr/local/lib/sasl2 /usr/lib/sasl2
In spite of this, I see the following error in my memcached server log:
mech: ``PLAIN'' with 26 bytes of data
SASL (severity 5): could not find auxprop plugin, was searching for 'sasldb'
SASL (severity 5): could not find auxprop plugin, was searching for 'sasldb'
My memcached.conf looks as below:
pwcheck_method: auxprop
auxprop_plugin: sasldb
mech_list: plain
log_level: 5
sasldb_path: /usr/lib/sasl2
What I can't understand is how I enable the auxprop plugin with berkeley db
for cyrus to read the config correctly?
Thanks and Regards,
Om Kale
