How to use IdentityMappingRUleType

[sinelabore]

Hi,

I want to call "AddIdentity()" on an object to add a user to a specific role.
The method requires an IdentityCriteriaType parameter if I understand it correctly.
My plan was to use IdentityCriteriaType and set its attributes criteriaType and criteria accordingly.

But the code line
identityMappingRuleType = ua.IdentityMappingRuleType()

triggers this error:

ValueError: 0 is not a valid IdentityCriteriaType

Which is ok, because criteriaType is an Enum whose first value is 1 (USERNAME). But how to use ua.IdentityMappingRuleType without triggering this error immediately before I even have the chance to set the attributes?

Is there a short example how to use this Type or do I make something wrong in general?

the enum is here:

which has no member 0!

i assume you should do something like

identityMappingRuleType = ua.IdentityMappingRuleType(ua.IdentityCriteriaType.UserName, "CreteriaString")

Hi, your link goes to the async codebase. And there the class IdentityMappingRuleType looks different.

In the "non async" version the class init code is as follows:

def __init__(self): self.CriteriaType = IdentityCriteriaType(0) self.Criteria = None self._freeze = True

Should that be fixed -> 1 instead of 0?
