I'm implementing a configuration for Windows Authentication on SPS, and this
one doesn't work and the SPS Agent reports :
[SmNtc::getCredentials][Request for SSPI NTLM with Safari browser Authentication]
[CSmSSPIServer::getCredentialsNTLMAuth][ SMNTLMCOOKIE TYPE 3 ]
[CSmSSPIServer::processNTLMRequest][AcceptSecurityContext returned : 0x80090311]
[CSmSSPIServer::getCredentialsNTLMAuth][processNTLMRequest Type 3 failed with -2146893039.
Re-requesting for authentication]
The SPS Agent reports this error as it cannot get the NTLM token from the browser.
Configure the Browser for automatically logon with current username and password
to solve the issue
