Unable to install CA Workload Automation AE Server/Client/SDK/Agent. The installation fails with the following message:

Reason: An unknown user or group identifier might have been used to install a file.
Action: Create the user or group account before installing the product

We have validated that both the user and group, specified as the owner of the product during the install (Owner and Group Settings question in the WAAE installer), are valid LDAP user and group.


Error received during CA WAAE Agent installation when specifying user id "oracle" and group "oinstall" as the owner of the product.

<Please see attached file for image>


CA Workload Automation AE r11.3.5 or higher on all supported UNIX/Linux platforms.


This error happens if the owner and/or group name specified as the owner-group during the installation is/are not present in the /etc/passwd (user) and /etc/group (group) files on the UNIX/Linux server, although that user and group may exist in an external group database such as NIS or LDAP.

Since the useradd and groupadd  system command denies the group creation request if the group already exists in an external group database, checking the option "[x] Create the Owner and Group Accounts" during the installation does not help.

In the aforementioned example, the group "oinstall" is a valid group on the LDAP server, however the /etc/group file did not contain an entry for "oinstall".


Add the desired user to the /etc/passwd file and/or the group name to the /etc/group file on the UNIX / Linux server and redo the CA WA AE installation. You may remove these entries from the /etc/passwd and /etc/group files after the installation is complete.

--- OR ---

The default owner name is autosys and the default group name is sys. Complete the installation using the default owner and group first and then change the owner and group of product files (default directory: /opt/CA/WorkloadAutomationAE) using system commands chown and chgrp.
