If the password for the idradmin account is unknown, you must reset it to the default empty value before you can specify another password value.
Stop the Server Manager Main server.
Stopping the Server Manager stops the running replication tasks and schedules.
Start the Server Manager Main server with the reset_idradmin command-line parameter. Use the following commands:
On Windows:
server_manager.exe reset_idradmin
On Linux or UNIX:
./server_manager.sh reset_idradmin
The Server Manager resets the password for the idradmin account to empty and then stops. Also, if the idradmin account was locked because you reached the maximum number of failed login attempts set by the MaxLoginAttempts property, the idradmin account is unlocked.
Restart the Server Manager Main server.
From the Data Replication Console, connect to the Server Manager Main server as the idradmin user using the empty password.
