We've recently integrated external software with our AX system using AIF inbound ports with an HTTP adaptor.
Middleware is running periodic SQL queries pulling delta data from AX. Then, the middleware uploads this data to the external system. After the data is posted to the external system, the middleware writes back the externalIDs to AX via an HTTP AIF inbound port. During this writeback process, AX sometimes throws a 401 error, and the integration fails. The AD account associated with the AIF calls also locks out.
Could anyone please provide advice on what is causing this?
We tried updating our AIF to accept an array of 100 records rather than 1 record per externalID. That helped reduce the frequency of the issue, but this is still occurring with any large data load and also during normal business processes once per week.
We've checked multiple servers (SQL, middleware...) to verify the associated AD credentials are correct.
Any help is appreciated.
Thanks!
