[Dovecot] error 89 when loading plugin

Hi,

I'm very confused - that's not too difficult for me.

I have written a small plugin change_passwd_plugin.c
I would like this custom IMAP command to be available to all users.

The code contains the following.

void change_passwd_plugin_init(void)
    {
	command_register("XCHANGEPASSWORD", cmd_xchangepasswd, 0);
	str_append(capability_string, " XCHANGEPASSWORD");
    }

void change_passwd_plugin_deinit(void)
    {
	command_unregister("XCHANGEPASSWORD");
    }

% nm
0000000000000920 T change_passwd_plugin_deinit
00000000000008ec T change_passwd_plugin_init
0000000000201248 D change_passwd_plugin_version

dovecot.conf
mail_plugins = change_passwd_plugin
mail_plugin_dir = /usr/lib/dovecot/imap
imap_capability = XCHANGEPASSWORD

%ls -la /usr/lib/dovecot/imap
ls -la /usr/lib/dovecot/imap
total 28
drwxr-xr-x 2 root root  4096 Aug  1 16:03 .
drwxr-xr-x 3 root root  4096 Aug  1 10:51 ..
-rwxr-xr-x 1 root root 16969 Aug  1 16:03 change_passwd_plugin.so


During login I see the following

/var/log/maillog
Aug  1 16:13:00 development dovecot: IMAP(test): Loading modules from directory: /usr/lib/dovecot/imap
Aug  1 16:13:00 development dovecot: IMAP(test): Plugin change_passwd_plugin not found from directory /usr/lib/dovecot/imap
Aug  1 16:13:00 development dovecot: child 29715 (imap) returned error 89

I don't understand why I'm getting an "error 89" reported.
The login session is terminated by dovecot when the error occurs.

Any assistance or ideas would be appreciated.

Regards,

John
