After installing Active IQ Unified Manager on Linux the maintenance user fails to authenticate

Applies to

• Active IQ Unified Manager (AIQUM) 9.6+
• Red Hat Enterprise Linux (RHEL)
• CentOS

Issue

• The correct procedure has been following as per the Active IQ Unified Manager documentation to set up the maintenance user for Active IQ Unified Manager in a Red Hat or CentOS platform.
• After the install has been completed, logging into the Unified Manager UI with the default maintenance user credentials (see Installing Unified Manager for default  credentials) results with error message: Authentication Failed. Please verify Username and Password.
• Changing the umadmin credentials (as documented in Changing the umadmin password on Linux systems) still causes the authentication to fail from the Unified Manager UI.
• The following may also be seen in the RHEL/CentOS secure log  (located in /var/log/secure):

Apr 01 13:10:03 unifiedmanager-servername sudo[13074]: pam_unix(sudo:auth): conversation failed
Apr 01 13:10:03 unifiedmanager-servername sudo[13074]: pam_unix(sudo:auth): auth could not identify password for [jboss]
Apr 01 13:10:03 unifiedmanager-servername sudo[13074]: pam_succeed_if(sudo:auth): requirement "uid >= 1000" not met by user "jboss"
Apr 01 13:10:05 unifiedmanager-servername sudo[13074]:    jboss : command not allowed ; TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/etc/init.d/ocieau start

• When entering the following command in MySQL (refer to KB article How to access MySQL within all Active IQ Unified Manager platforms to access MySQL), an empty set is observed within the authorizationunit table as shown below. 

mysql > select * from ocum.authorizationunit;
Empty set (0.00 sec)
