It's me again
Next thing we faced is that there is a lack of password sync regarding UNIX and SAMBA passwords when zimbra_posix and zimbra_samba are installed. There are 3 ways of password changing:
1) from Windows machine: if ldap password sync is YES then:
[2010/01/10 15:24:57, 0] passdb/pdb_ldap.c:ldapsam_modify_entry(1651)
ldapsam_modify_entry: LDAP Password could not be changed for user XXX: Insufficient access
but Windows says 'Success' however next time "..your old password doesn'r match". Looks like something went wrong and now LM/NT Passwords are broken.
2) from Linux machine via passwd : neither userPassword not LM/NT. See my later post about it.
3) from ZCS UI - but only userPassword is changed. We read about this issue and found this link: Get or contribute Zimlets, UI themes, and languages in the Zimbra Gallery - zimbraSambaPassword Extension however it's closed and for 5.x not 6.x.
To recap: most valuable for us are: Windows and ZCS UI. Do you have this extension available for 6.0.x? or maybe there is some workaround for password changing from UI?
