Question

IIS

SSO-domain auth

- Pub1 (everything is fine)
- Pub2 (everything is fine)
- Pub3 (weblogic) iisproxy,iisredirect and etc -- problem

= Problem
On IIS failed on one of the servers on WAS
-----
EventID System 5172
The Windows Process Activation Service encountered an error trying to read configuration data from file '\\?\C:\Windows\system32\inetsrv\config\redirection .config', line number '13'. The error message is: 'Failed to decrypt attribute 'password'
'. The data field contains the error number.
---------
In the 13th line, the login and password field is encrypted "[enc: IISRsaProvider:"
Removing the entire encryption block and changing the line to the password in clear text in the configuration file gives the same error on the 13th line, although there are already 9 or 8 lines
. Framework is used.
All versions are checked and correspond to all specified parameters.
Previously, CA + clents domain certificates were changed for applications and publications, there were issues with Weblogic, they decided it worked. It fell apart after a couple of days.
MachineGUID was checked, and so on. A week spent on Google and to no avail. The question is that there is no reaction at all to the manipulation of the config on whom he swears. There are no other places.

The economy is heaped up and there is really no documentation. I know all the moments after solving the problems.
If you have any questions write I will try to answer or supplement the question with arguments.
