Editing a User

Before you edit a user's information, review Username and Password Requirements.

To edit a user's details, including their password:

1. On the top-right corner, select Users and Groups.
2. Select a user by clicking anywhere in the user record.
3. Choose Edit user.
4. In the dialog box that opens, edit any fields except Username.
5. Select Update user.

To edit the password of the default user system:

1. Change the password for the user system in Users and Groups.
2. Confirm that the current Java is set to the OpenJDK package bundled with the Tamr software package, and that the environment variable JAVA_HOME is set.

which java
<tamr-home-directory>/openjdk-8u222/bin/java
echo $JAVA_HOME
<tamr-home-directory>/openjdk-8u222

If those aren't set, run the following commands (assuming bash shell):

export JAVA_HOME=<tamr-home-directory>/openjdk-8u222
export PATH=$JAVA_HOME/bin:$PATH

3. Encrypt the new system user's password using the utility encrypt.sh as follows:

cd <tamr-home-directory>/tamr
./encrypt.sh -AES256
Please enter a password to encrypt:

4. Set the configuration variable TAMR_SYSTEM_PASSWORD to the encrypted output generated in the previous step the administrative utility. See Setting Configuration Variables.
5. Restart Tamr and its dependencies. See Restarting.

Switching Between Internal and External User Management

Tamr synchronizes user information and passwords for externally-managed users each time they log into Tamr. You cannot edit user information or passwords for these users unless you switch to managing the users internally. When users are managed internally, Tamr does not query any external systems for updates on name, email, or password. Instead, it uses the information and credentials stored in Tamr. If a new password has not been set in Tamr for the new internal user, the previous external password continues to be used.

Note: Internally-managed users can later be successfully changed to external management only if the usernames match exactly between Tamr and the external system. You can toggle this at any time, but you must ensure that the usernames match exactly (case sensitive) in order to avoid creating duplicate users. Users managed externally in the past can log in with either their externally-managed password, or with the password of their choice when switching to internal management.

To toggle between internal and external user management for a given user:

1. On the top-right corner, choose Users and Groups.
2. Select a user by clicking anywhere in the row describing them.
3. Choose Edit user.
4. In the dialog box that opens, choose the toggle to change between internal and external user management for the selected user.
5. Select Update user.
