 Cannot set the correct ownership on /home/autosys for autosys
 Please check that the autosys user is a part of the appropriate domain users group.

Cause

The groupname "Domain Users" is somehow interfering with the chown operation of the Directory configuration. 

Resolution

1) Backup and then update /etc/group with below

users:x:123456:             ## 123456 is the GUID for Domain Users group

2) Check the identify of the Unix (say dsa) user in question:

id autosys

3)  The user and group should now change from “domain users” to “users”
 

4) Retry install again

 

Additional Information

1) There are additional requirements in the Directory documentation:  installing-ca-directory    

2) Whatever the dsa Unix user is, dsa or autosys or some custom name, that needs to be used, the description (locally in /etc/passwd file or LDAP user) must be 'DXserver Administrator' (it is case sensitive)
