unable to create user - character limit 20

[hdep]

Hello,

I try to create a user as following :

ou = pyad.adcontainer.ADContainer.from_dn("OU=Users, DC=company, DC=local")
new_user = pyad.adcontainer.ADUser.create("Anne XXXXXX XXX XXXXXXXX", ou, password="Passw0rd", upn_suffix="@company.local", optional_attributes = {"samaccountname":"htest","userPrincipalName":login + "@company.local","givenname":"Hugo","sn":"Test","displayName":"Hugo Test"})

I got an error :

c:\>C:\Users\hugo\Desktop\user_ad.py
Traceback (most recent call last):
  File "C:\Users\hugo\AppData\Local\Programs\Python\Python35-32\lib\site-pack

ment.\r\n', None, 0, -2147024865), None)

During handling of the above exception, another exception occurred:

After some test it appears that it works if name field is 20 character max. Are you aware of this limitation ? from windows point of view it should be OK.

It seems that this is a windows 2012 limitation for samaccountname (20 character max). So there is something I don't understand with this lib about the first field.
