Hey @73VW,

The reason is that I presumed that Django would be set to use the email field as the auth user ID. I see that this is a useful change, so I'll merge it and will release a version at some point.

in the users.py file I was able to get my application to put both the username and email field correctly. I am using mailman with django so idk if this will particular pertain directly to anyone else situation. The part with the asterisks is where I want to bring attention to I added that to the file and on top of that I added what the OP put in a hook method with one tweak please see below. The combination of these two things is what is working for me currently. In case someone else has this issue I want to make sure I clearly explain.

In the user.py file find the section with the def seen below at the end of that def include what the asterisk are around the og code just reads as return "user_id.lower() if user_id else None"

Once you've made that change then just create a .py file in the django_saml2_auth path insert the code below the def post create user. save it

make sure its called correctly in your settings.py file and then it should work. i havent seen any consquences on my end yet for this change.. @mostafa wants i can post the entire file but again i only made those two changes..

def get_user_id(user: Union[str, Dict[str, Any]]) -> Optional[str]:
"""Get user_id (username or email) from user object

Args:
    user (Union[str, Dict[str, Any]]): A cleaned user info object

Returns:
    Optional[str]: user_id, which is either email or username
"""
user_model = get_user_model()
user_id = None

if isinstance(user, dict):
    user_id = user["email"] if user_model.USERNAME_FIELD == "email" else user["username"]

if isinstance(user, str):
    user_id = user

****return user_id if user_id and '@' in user_id else None****

def post_create_user(user_dict, *args, **kwargs):
user_model = get_user_model()
user_id = user_dict.get(user_model.USERNAME_FIELD)
user = user_model.objects.get(username=user_id)
user.email = user_id
user.username = user_id.split('@')[0]
user.save()

Hey @dejonestheadmin,

Please do not post the entire code base in a comment, instead create a fork and change that or use GitHub Gists to show the changes.

@mostafa my apologies for the mistake I will try to make the changes the appropriate way

@mostafa I got it figured out 100% finally Ill update code asap most likely send what I have tonight after work

Okay after testing with multiple users I have a lot of confidence that this works just as expected I will post the entire code or make the changes where deemed appropriate but I believe and please correct if I am wrong but I can post at least a snippet of the areas that need changes
ALL CHANGES ARE ONLY MADE IN THE user.py file.
Change #1 can be found in 'def create_new_user'
user = user_model.objects.create_user(email.split('@')[0], **kwargs)
user.is_active = is_active
user.is_staff = is_staff
user.is_superuser = is_superuser
user.email = email
user.save()

Change #2 can be found in 'def get_user'
return user_model.objects.get(**{id_field: user_id.split('@')[0]})

Ill be honest again im very very new to messing with any of these technologies but for me this did solve the problem. I will put the full code in the appropriate locations. Apologies again if this type of info doesnt belong in this section I am just overly excited that I could finally figure something like this out .. although i know its small compared to the things other brilliant minds that have helped here as well.

This also should allow the username to be created without the @domain.com and let the email address remain as is
