I'm having trouble hunting down an issue where an ASP.NET 4 application fails while trying to get user groups for a given user from time to time. The application pool associated with this application is setup to run under ApplicationPoolIdentity.
Exception Info
System.DirectoryServices.DirectoryServicesCOMException
HRESULT: 80072020
Message: An operations error occurred.
Extended Message: 000004DC: LdapErr: DSID-0C0906E8, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1db1
Stack Trace
System.DirectoryServices.DirectoryEntry.Bind(Boolean)
System.DirectoryServices.DirectoryEntry.Bind()
System.DirectoryServices.DirectoryEntry.get_AdsObject()
System.DirectoryServices.DirectorySearcher.FindAll(Boolean)
System.DirectoryServices.DirectorySearcher.FindOne()
95%-99% of the time, this function works fine, but from time to time, it just starts failing. When I change the application pool to use LocalSystem or NetworkService, it starts working. When I change back to ApplicationPoolIdentity it begins failing again. The only way to get the site working again with ApplicationPoolIdentity is to reboot the server.
I was able to find a similar issue here , but the resolution was a reboot as well. I'd like to find a more permanent solution short of changing the identity of the application pool.
虽然重新启动将暂时解决此问题,但有一个Microsoft修补程序KB2545850 ,可以永久解决该问题。
