User Maintenance Considerations

In general, user maintenance in a horizontally scaled system is the same as in a single-machine system. However, there is one major difference: you must maintain identical OS user accounts (same user names and passwords) on all machines or nodes in the horizontally scaled system. This is because user definitions in the Lawson system are linked to OS users. Since users can access any of the nodes of the horizontally scaled system, the same OS user accounts must be available in each case. This impacts the following cases:

• When you add a user to the Lawson system who needs to be linked to a unique OS user, you must add the OS user to all nodes in the cluster.

• If you need to make changes to any environment variables that affect users, you must edit the etc/lawson.env file on each node in the cluster.

• If you want to delete every trace of a user from your system, you must delete the OS user accounts from all nodes in the cluster, as well as the user information in the Lawson system.
