Problem Description :
User getting below error while login into Director. Below is error message
Error : Failed to extract Claims Identity from a given token.
ID4175 : The issuer of the security token was not recognized by the IssuerNameRegistery. To accept security tokens from this issuer, configure the IssuerNameRegistry to return a valid name for this issuer.
1) Close the client application
2) Edit the applications config file (for example Director’s config file is located in C:\Program Files (x86)\Bentley\eB\Directorand called eB.Application.Director.exe.config)
3) Delete the entry: <add key="Bentley.eB.StsIssuerCertificate" value="A5A2F1CB135FAB96D43B7DEA28E3AAC7F60CF814" />
4) Also look inC:\Users\<username>\AppData\Roaming\Bentley\eB. If the ims.bentley.com.FederationMetadata.xml file exist please delete it.
Hope this helps
