How to Reset the Directory Manager Password on RHEL 7 / CentOS 7

Reset the Directory Manager Password

In the digital world, it’s a common practice to remember passwords. However, due to the sheer number of passwords we need to remember, it’s not uncommon to forget one or two. As a system administrator, forgetting the password to manage the directory service can be a significant issue. This password is usually the admin or Directory Manager’s password.

The Directory Manager’s password is stored in the directory server configuration file and can be modified by editing the file. If you forget this password, don’t worry, it’s relatively straightforward to reset it. This comprehensive guide will walk you through the process of checking or resetting the Directory Manager password on RHEL 7 or CentOS 7.

Step-by-Step Guide to Reset the Directory Manager Password

Step 1: Stop the Directory Service

The first step in this process is to stop the directory service. If the server is running when the configuration file (dse.ldif) is modified, the changes will be lost and not applied. Use the following command to stop the service:

# systemctl stop [yourinstance]

Step 2: Generate a New Password

Next, you need to generate a new password using the pwdhash command:

# /usr/bin/pwdhash yournewpassword

This command will print out the hashed password string using the default directory manager password hashing scheme for your instance (SSHA by default).

Step 3: Open the Configuration File

In the configuration directory, open dse.ldif using the following commands:

# cd /etc/dirsrv/slapd-instancename
# vi dse.ldif

Step 4: Replace the Old Password

Locate the nsslapd-rootpw parameter in the configuration file. Replace the old directory manager password with the new password you generated in step 2:

nsslapd-rootpw: {SSHA}yournewhashedpassword

Step 5: Save Changes and Start the Directory Service

After replacing the old password, save the changes and start the directory service using the following command:

# systemctl start [yourinstance]

Step 6: Verify the Password

Finally, log into the Console again as Directory Manager and verify the password.

Commands Mentioned

  • systemctl stop [yourinstance] – Stops the directory service
  • /usr/bin/pwdhash yournewpassword – Generates a new hashed password
  • cd /etc/dirsrv/slapd-instancename – Navigates to the configuration directory
  • vi dse.ldif – Opens the configuration file
  • systemctl start [yourinstance] – Starts the directory service
