Issue:
We need to know which permissions are required in order to install CA Identity Manager 14.1 on RHEL 7.

we know, CA Directory 12.6 supports non-root install. Is it possible to say the same for CA Identity Manager 14.1? If not, which permissions are required to install the product without using root?
Resolution:
For IM: Customer will need to create a user and put it in sudoers list,

the permissions required for the install directory for this user EX" /otp/CA" are '777' - this is because the installation is writing IDM's files into that folder.

For CA Directory and CA Provisioning Directory if you check your users list, you will see a new users called DSA and imps, these users have permissions to the directory where CA Directory and CA Provisioning Directory was installed.

These users are created by the installer:
>dsa< to manage DSAs
>imps< to manage provisioning server

You can disable them, copy their profile to the new user, then change services to point to the new users if these usernames do not meet your service accounts naming convention.
