Overlays syncrepl and smbk5pwd

[Francesco Storti <francesco.storti@ubiquity.it>]

Hi,
I am using both syncrepl (for replication) and smbk5pwd (for password 
synchronisation between samba and ldap account) overlays.
I have configured replication in the simplest way: a read-only producer 
that forwards updates to the provider thought updateref.
If I change my password thought  passwd command on a client with pam 
modules configured for gaining information from the provider everything 
works fine (userPassword, sambaLMPassword and sambaNTPassword are 
correctly syncronized).
Instead, if I change my password thought  passwd command on another 
client with pam modules configured for gaining information from the 
consumer only the userPassword is changed.
I do not understand why.
Has someone experimented the same problem?
Thank you in advance.
