I suspect that authentication or authorization fail, most likely because the LDAP configuration needs some more adjustments. When MWG successfully connect to the LDAP server, this does not mean that authentication and/or authorization work.
Did you use the "authentication test" in the LDAP settings to verify your configuration with a test user?
Maybe you can share some more details about your LDAP setup and rules for authentication to allow us to better understand what the issue is.
We are facing the same issue. Please let me know what details do you require.
we are ruuning short of time. Immediate reply is appreciated.
I would suggest opening a case with a tcpdump.
To perform a tcpdump go to Troubleshooting > Packet tracing, then enter '-s0 -i any' as the CLI parameters. Click "tcpdump start", reproduce the issue (please only have the tcpdump running for less that 30 seconds), click "tcpdump stop", then send the resulting file to support ticket.
Please also include the client IP you tested from when reproducing the issue and also a feedback file.
