SPSecurityTokenService.PopulateOut putIdentity() failed to lookup UPN for user
Hello, I have a windows 7x64 developer box. On this I have installed SQL 2008R2 developer edition and Sharepoint 2010 ent. I run all the Sharepoint services under my local admin account "win7dh\administrator" When I enter a search term in the search box I get this error: SPSecurityTokenService.PopulateOutputIdentity() failed to lookup UPN for user 'WIN7DH\Administrator': System.ComponentModel.Win32Exception: No mapping between account names and security IDs was done at Microsoft.SharePoint.Win32.SPSecur32.GetUserNameEx(EXTENDED_NAME_FORMAT nameFormat) at Microsoft.SharePoint.IdentityModel.SPSecurityTokenService.PopulateOutputIdentity(SPRequestInfo requestInfo, IClaimsIdentity outputIdentity) I get this error in all site types.Can anyone tell me how to fix this issue? Thanks in advance Danny
