Checked with Roland..
The last login time (zimbraLastLogonTimestamp) gets updated as often as the global config value:
zimbraLastLogonTimestampFrequency: 7d
Mainly to keep LDAP writes down, and because most people only need to ask queries like "show me all accounts that haven't logged in in 30/60/90 days".
So the short anwser is you can get this from LDAP. |
