I need to store last authentication time for imap login.
A simple solution is to look at the mtime timestamp on the 'cur'
subdirectory of the Maildir. This is because every time the user logs in,
any mail in new/ is moved to cur/, and this updates the timestamp on cur/.
This doesn't work if the user has no new mail, but you can add a simple
patch to update the cur/ directory in that case.
The attached patches are a couple of years old, you'll have to see if they
still apply cleanly. They have been posted before, e.g.

For performance reasons, I've disabled log of timestamp access in the Maildir's partition with noatime option, this solution doesn't work in my setup. You misunderstand. There are three inode timestamps: ctime - when file's status was last changed mtime - when file was modified atime - when file was accessed Disabling atime updates doesn't affect the other two. mtime is always updated when a file or directory is changed. 'man 2 stat' for more info. Brian. - Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!

Re: [Courier-imap] Imaplogin - lastauth
Jeronimo, Change your LDAP schema to add an attribute called LastMailCheckTime (or any other name you would like). You can then add this code to the auth_ldap_do3 function in authldaplib.c after the authentication bind is successful. Note that I do an async ldap_modify so that authdaemon does not block waiting on the modify. I wrote this up quick so you may want to double check it. Any questions, let me know. ---Aaron LDAPMod *mod_ctime_send[2]; LDAPMod mod_ctime_up; char *ctime_attribute_name=LastMailCheckTime; char ctime_value[512]; char *mod_update_vals[2]; time_t m_check_time; m_check_time=time(NULL); mod_ctime_send[0]=mod_ctime_up; mod_ctime_send[1]=0; sprintf(ctime_value,%u,(unsigned int) m_check_time); mod_ctime_up.mod_op=LDAP_MOD_REPLACE; mod_ctime_up.mod_type=ctime_attribute_name; mod_ctime_up.mod_values=mod_update_vals; mod_update_vals[0]=ctime_value; mod_update_vals[1]=NULL; //ASYNCHRONUS UPDATE ldap_modify(bindp, dn, mod_ctime_send); On Thu 07/03/08 16:57 , Jeronimo Zucco [EMAIL PROTECTED] sent: wrote: Carlos, Why not make a small LDAP schema change and perform an ldap modify? You can place that code right in authdaemon. That is what I did and it has worked fine for years with more than 75,000 mailboxes. This is what I would like to do in my courier setup. How did you do it? Can you give some information about it ?
