I am trying to authenticate on my FBA site (On-Prem SP2013) using Content Matrix Extensions Web Service. However, I am getting the below error -
MEWS Url: http://myserver:9090/sites/fbasite/_vti_bin/ml/126.96.36.199/mlspextensions.asmx. Exception: Server was unable to process request. ---> Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) ---> System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
I am able to successfully authenticate with Native Web Service url - http://myserver:9090/sites/fbasite/_vti_bin/authentication.asmx using this approach.
However, I can see that '/authentication.asmx' does not exist for '/ml/188.8.131.52/' and I also do not see any corresponding Auth or Login method in '/mlspextensions.asmx'
[Note: My FBA site is also having Windows auth enabled.]
Can someone please help with this authentication issue.
