How to check accounts that are not active in zimbra
Introduction
Managing email accounts effectively is a critical task for system administrators using Zimbra, an open-source collaboration suite. Identifying inactive accounts ensures optimal server performance, security, and storage efficiency. In this article, we’ll explore how to check accounts that are not active in Zimbra using a streamlined approach.
Why Check for Inactive Accounts in Zimbra?
Benefits of Identifying Inactive Accounts
Inactive accounts can lead to various issues, including:
Wasted Storage: Dormant accounts consume server space.
Security Risks: Unused accounts may become vulnerable to unauthorized access.
Operational Efficiency: Regular cleanup enhances system performance and maintainability.
By identifying and addressing inactive accounts, administrators can maintain a secure and efficient email environment.
Step-by-Step Guide to Checking Inactive Accounts in Zimbra
Prerequisites
Before you begin, ensure you have:
Admin Access: Permissions to execute commands on the Zimbra server.
Command-Line Interface: Access to the terminal or SSH.
Zimbra Version Compatibility: Confirm the commands work with your Zimbra version.
Using Zimbra’s Built-In Command
Zimbra offers a simple command to list all accounts:
zmprov -l gaa
This outputs all email accounts on the server. To filter inactive accounts, combine the command with additional parameters.
Checking Last Login Activity
Run the following command to check when users last logged in:
zmprov sa '(&(zimbraLastLogonTimestamp<=[timestamp]))'
Replace
[timestamp]with the desired date threshold (e.g., 90 days ago).Example:
zmprov sa '(&(zimbraLastLogonTimestamp<=20230901000000Z))'
This command lists accounts that haven’t logged in since September 1, 2023.
Advanced Filtering Techniques
Using Zimbra’s Search Attributes
Enhance your search with additional attributes:
Account Status: Identify locked or disabled accounts:
zmprov sa 'zimbraAccountStatus=closed'
No Login Records: Find accounts without a login history:
zmprov sa '(!(zimbraLastLogonTimestamp=*))'
Automating the Process with Scripts
Shell Script for Inactive Account Detection
Create a script to automate inactive account checks:
#!/bin/bash
threshold_date=$(date -d '90 days ago' +%Y%m%d000000Z)
echo "Accounts inactive since $threshold_date:"
zmprov sa "(&(zimbraLastLogonTimestamp<=$threshold_date))"
Save the script as
check_inactive_accounts.sh.Make it executable:
chmod +x check_inactive_accounts.sh
Run the script:
./check_inactive_accounts.sh

zmaccts | grep closed | grep @ | awk '{ print $1 }' | while read ACCOUNT
do
QUOTA_TOTAL=`zmprov ga ${ACCOUNT} | grep "zimbraMailQuota" | cut -d ":" -f2`
QUOTA_USAGE=`zmmailbox -z -m ${ACCOUNT} gms`
HOSTED_ON=`zmprov ga ${ACCOUNT} | grep zimbraMailHost | awk -F: '{ print $2 }'`
LAST_ON=`zmprov ga ${ACCOUNT} | grep zimbraLastLogonTimestamp: | awk -F: '{ print $2 }' `
echo "${ACCOUNT} ${QUOTA_TOTAL} ${QUOTA_USAGE} ${HOSTED_ON} ${LAST_ON} "
done
