I am trying to use generateToken with my arcgis portal.
I have two accounts :
Account1 : user/password
Account2 : windows authentification
When I use the endpoint https://arcgisportal/portal/sharing/rest/generateToken with account1 (user/password), it generates me a valide token and it works fine
But I can not generate a token for my windows account, it indicates me that the username or password is invalid.
Do you know where is the problem ?
