UBLOX_AT_CellularContext appears to use wrong authentication for Stream sims

[NeilMacMullen]

Description

I don't know whether this is really a bug in the Stream network but attempting to connect using a Stream (ARM) sim with

iface->set_credentials("stream.co.uk", "streamip", "streamip");

fails unless PAP is used in the UBLOX_AT_CellularContext constructor....

UBLOX_AT_CellularContext::UBLOX_AT_CellularContext(ATHandler &at, CellularDevice *device, const char *apn, bool cp_req, bool nonip_req) :
    AT_CellularContext(at, device, apn, cp_req, nonip_req)
{
    // The authentication to use
    //PAP seems to be required as the default in order for STREAM sims to work
	_auth = NSAPI_SECURITY_PAP;
}

What target you are using ? and if you have logs that will be helpful

[NeilMacMullen]

@fahim-ublox It's a custom mbed target. The modem is G450. I'll see if I can collect logs next time I'm working on this but it may be a while.

@ciarmcom this can be linked to this issue: #10551
We will add an API for changing the authentication type.

I don't follow? Please link it in the jira

@0xc0170
#10551 will not fully address this issue. Once an API is provided for application to be able to set authentication type, we will be using _authentication_type in our class to provide the said functionality.

#10877 updates auth configuration and you can use set_authentication_type to set auth type from main application.

[wajahat-abbas]

@NeilMacMullen Can you please have a look and see if #10877 fixes this issue?

Is their any particular reason that the SIM card doesn't provide all this information.
Embedded cellular seems to require a lot of manual configuration...
