Dear SAP B1 colleagues,

Could the crushed for the disabling of the SAP Business One ace idiosyncratic from accessing immoderate institution beryllium the pursuing :
It mightiness beryllium owed to aggregate failed attempts that the idiosyncratic has been disabled from SLD

I don't judge it due to the fact that :

1. He is the lone idiosyncratic who disabled among much than 100 users.

2. What does SLD bash with SAP B1 ace idiosyncratic login attempts? arsenic I know, the progressive directory should artifact the idiosyncratic from signing successful erstwhile his logging attempts neglect galore times, but not SLD !!!

3. If you are blocked by progressive directory, you are not going to person this connection erstwhile you log in. Please spot the representation down.

What are your opinions?
