DUAS5: Impossible to start Engines

Issue/Introduction:

Affects Release version(s): 5

On a Linux / Unix server were Dollar Universe uses a LDAP user as DUAS admin account (ie univadm), after an operation on LDAP or after having patched the OS where DUAS had not been previously correctly stopped it is impossible to restart the DUAS engines (LAN, EXC, SUR and CAL).
Even if it seems that LDAP is operational again.

The user starting the process (univadm) is not present in /etc/passwd file.

Cause:

System / LDAP configuration issue, Dollar Universe User cannot be found in the /etc/passwd or LDAP server

Environment:

Dollar universe 5.x
OS: Linux / Unix

Resolution:

If:
- You have tried to razfic different files (u_fmpi50)
- You see that uxlst atm command can only be executed by root.
- You see that a reorganization doesn't help.

It means that the problem is certainly coming from LDAP configuration and the root cause is probably related to the LDAP Server or /etc/passwd

In order to fix the issue, either fix the LDAP configuration or simply ask the System Administrators to create the user locally ( adding it to /etc/passwd).
