[gdal-dev] OGC services and credentials

[Michał Kowalczuk]

Hi GDAL friends!

Why service credentials (username & password) can not be entered with open
options (*-oo UserPwd=user:pass*) when working with OGC services (tested
against WMS)?

I know there is a config option *GDAL_HTTP_USERPWD=value* but it's not
clean solution in my opinion. Credential should be related to and owned by
the dataset not the global environmental variable. What if I use more than
one services that need credentials?

I know there is a "UserPwd" XML tag when using xml as an open path, but
this limits the use of other open methods (
https://gdal.org/en/latest/drivers/raster/wms.html#xml-description-file).

So, the following returns dataset info
*gdalinfo "WMS:sample_wms_service?request=getcapabilities&service=wms"
--config GDAL_HTTP_USERPWD=user:pass*

and the following:
*gdalinfo "WMS: sample_wms_service?request=getcapabilities&service=wms" -oo
UserPwd=user:pass*
returns error:


*ERROR 1: HTTP error code : 401ERROR 1: Error returned by server : HTTP
error code : 401 (0)gdalinfo failed - unable to open* ...

Unfortunately, I can not share the sample service and it's credentials, but
it is not needed for answer my general question.

Thank you in advance for your interest in the problem
