ldapdb_canonuser_plug_init invalid parameter supplied

[Alexander N. Lunev]

Hello everyone!

I'm stuck in the problem that cyrus-sasl library doesn't recognize 
ldapdb auxprop plugin.

I have these packages installed on FreeBSD-10.3R:

# pkg info | grep sasl
cyrus-sasl-2.1.26_13
cyrus-sasl-ldapdb-2.1.26_5
cyrus-sasl-saslauthd-2.1.26_3
openldap-sasl-client-2.4.46
openldap-sasl-server-2.4.46_5

But pluginviewer only lists sasldb plugin, and not ldapdb:

# pluginviewer -a
Installed and properly configured auxprop mechanisms are:
sasldb
List of auxprop plugins follows
Plugin "sasldb" ,       API version: 8
         supports store: yes

And in logs i see this:

Oct 31 10:24:17 startsnto pluginviewer: ldapdb_canonuser_plug_init() 
failed in sasl_canonuser_add_plugin(): invalid parameter supplied
Oct 31 10:24:17 startsnto pluginviewer: auxpropfunc error invalid 
parameter supplied
Oct 31 10:24:17 startsnto pluginviewer: ldapdb_canonuser_plug_init() 
failed in sasl_canonuser_add_plugin(): invalid parameter supplied

In fact every sasl-linked program that run on system make such error 
message in logs (I have also nss_ldap configured, so every call to 
system functions about uid/gid is also produce this error):

ldapwhoami: ldapdb_canonuser_plug_init() failed in 
sasl_canonuser_add_plugin(): invalid parameter supplied
chown: ldapdb_canonuser_plug_init() failed in 
sasl_canonuser_add_plugin(): invalid parameter supplied
saslauthd[15698]: ldapdb_canonuser_plug_init() failed in 
sasl_canonuser_add_plugin(): invalid parameter supplied

But what's more intriguing is that ldapdb plugin is actually working! 
cyrus-imapd successfully authorizing users with this config file:

sasl_pwcheck_method: auxprop
sasl_auxprop_plugin: ldapdb
sasl_mech_list: cram-md5 digest-md5 plain login
sasl_ldapdb_uri: ldap://localhost/
sasl_ldapdb_id: cyradm
sasl_ldapdb_pw: somepassword
sasl_ldapdb_filter: (uid=%u)
sasl_ldapdb_canon_attr: mail
