LDAP Homedir location: Needs dovecot restart after change it

[Andre Luiz Paiz]

Dear group members.

I work with Dovecot and Openldap authentication. Sometimes users  
change departments and we need to alter their homedir location. Every  
time this process is needed, I perform this steps:

1 - Change homedir location in openldap
2 - Move homedir folder to the new location
3 - Re-apply permissions
4 - Remove user index folder

After I do that, users cannot authenticate unless I restart dovecot,  
process that I would like to avoid. Can you guys give a tip on what I  
need to change to avoid this last problematic step? After the restart,  
everything works.

Does the auth_cache feature also store the homedir location?
