WinCCOA 3.12 on Red Hat Enterprise Linux 7.1

[excl_kaz]

Hello. We installed Win??OA 3.12 on Redhat 7.1. When we to start UI-manager and WCCilproxy an error occurred:
WCCOAui PARAM SEVERE 207 Cannot load SLL library (libcrypto)
WCCOAui SYS FATAL 104 User name or password wrong, root
WCCILproxy SYS FATAL 158 Could not create the server socket on port =5678: No such file or directory
Other managers run normal. OpenSSL is installed.

Hello,

according to the online help WinCC OA 3.12 supports RedHat EL 6.4.
RHEL 7.1 is officially not supported.

Have you tried the same installation on RHEL 6.4?

The second log messages describes that the username and password defined in the config file or at startup of the user interface manager are not correct.
Please check the settings in your project.

Which version of OpenSSL do you have installed and are you sure that WinCC OA can find it? OpenSSL is notorious for not having a reliable library filename in various Linux distributions. You could use 'strace' to check where the manager is looking for it.

I would guess that all of these errors are caused by the missing OpenSSL library; the WCCILproxy definitely needs it for its server socket, and it is also used for password hashing (which could cause the "User name or password wrong" error).
