Cannot establish credentialed connection using `GIS(url, username, password)`

Hello! I am trying to connect to my organization's AGOL as a first step in creating a script. But I cannot get paste stage one.

I am using the Python within ArcGIS Pro (via the Python Window).

Running the following lines:

from arcgis.gis import GIS from arcgis.features import FeatureLayer gis = GIS(url = 'https://nngov.maps.arcgis.com', username='nne\\username', password='my_password')

I am met with this error:

--------------------------------------------------------------------------- Exception Traceback (most recent call last) In [10]: Line 2: gis = GIS(url = 'https://nngov.maps.arcgis.com', username='nne\\cameronam', password='my_password') File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\__init__.py, in __init__: Line 585: raise e File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\__init__.py, in __init__: Line 524: self._portal = _portalpy.Portal( File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\_impl\_portalpy.py, in __init__: Line 205: self.con = Connection( File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\_impl\_con\_connection.py, in __init__: Line 344: self._create_session() File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\_impl\_con\_connection.py, in _create_session: Line 691: self._session.auth = EsriWindowsAuth( File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\auth\_auth\_winauth.py, in __init__: Line 84: raise Exception("Please ensure gssapi is installed")

`gssapi` IS already installed, as confirmed when I went to the Python command prompt and tried to install it:

(arcgispro-py3) C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3>pip install gssapi
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: gssapi in c:\program files\arcgis\pro\bin\python\envs\arcgispro-py3\lib\site-packages (1.8.1)
Requirement already satisfied: decorator in c:\program files\arcgis\pro\bin\python\envs\arcgispro-py3\lib\site-packages (from gssapi) (5.1.1)

My colleague succeeded in establishing the connection using her creds on her own machine, without being thrown an error related to 'gssapi'.

gis = GIS("https://nngov.maps.arcgis.com", "nne\\her_username", "her_password")

Has anyone got any idea for a resolution?

There's a thread on this that might be of interest: Please ensure gssapi is installed - Esri Community

But an easy fix might be to just use gis = GIS("pro") instead.

Thanks, Joseph. Using gis = GIS("pro") withing Pro seems to have done the trick. But I assume its working correctly depends on my currently being logged into my Pro account. If I write this script in a Notebook, publish the Notebook to AGOL, and try to use it for the purpose of a scheduled task, the GIS connection would need to explicitly established with reference to the organization's AGOL url and someone's credentials. Does that sound right?

In an AGOL notebook, you can just use gis=GIS("home"). In fact, that might be preferred over hardcoded credentials. This way, credentials aren't exposed, and if you change your password, you don't have to edit your Notebook code.

That said, I think the bug that is discussed in the link I sent is probably not relevant in an AGOL Notebook anyway. Seems to be limited to Pro 3.1/Python API 2.2.0.3. But I could be wrong about that.

Thanks so much for your help. Good to know I can just use GIS("home") from within AGOL.
