Resolving EPMAT-7: Unable to Modify Access Permission of Password File: .prefs Error
On Linux servers, EPM Automate may display the following error messages:
EPMAT-7:Unable to modify access permission of password file: .prefsUnable to read password file: {0}. Access denied
This issue occurs when EPM Automate is unable to modify the .prefs file. Generally, when a session is active, EPM Automate generates a .prefs file in the working directory to support the session. When another user attempts to execute a command from the same directory, EPM Automate is unable to update the .prefs file that was generated for the session that is already in progress and owned by a different user. Because the new (second) user does not have the required permissions on the existing .prefs file, EPM Automate displays this error message.
Always use the logout command to terminate the session. The .prefs file is removed when a user logs out. Additionally, each user should run EPM Automate from a different working directory.
