After the password leak in 2019 Telia revoked the local access for user tadmin
:
<cwmp:SetParameterValues xmlns:cwmp="urn:dslforum-org:cwmp-1-0">
<ParameterList SOAP-ENC:arrayType="cwmp:ParameterValueStruct[5]">
..
<ParameterValueStruct>
<Name>Device.Users.User.1.X_ADB_LocalAccessCapable</Name>
<Value xsi:type="xsd:boolean">0</Value>
</ParameterValueStruct>
