was that gdb output helpful? Is there any other way I can help solve this?

odd, nmon did not crash when run via gdb. I was however able to recompile with -g (and without -03) and it did still segfault when run normally. Then I ran gdb with the binary and coredump to generate the following output also: I am not mounting/unmounting while nmon is running. # gdb ./nmon_x86_rhel75 coredump GNU gdb (GDB) Red Hat Enterprise Linux 8.2-19.el8 Copyright (C) 2018 Free Software Foundation, Inc.

Sorry about that. unsafe-but-sanitized log attached (auth is set to "Auto).

There are two obvious errors: (12:19:23) sipe: webticket_token: ADFS authentication failed - assuming Multi-Factor Authentication (MFA) (12:20:46) connection: Connection error on 0C37ACA0 (reason: 2 description: Certificate request to https://lsweb.example.com/CertProv/CertProvisioningService.svc/WebTicket_Proof_SHA1 failed) Log attached

Anonymized log attached (pidgin_sipe_sso.txt: using "TLS-DSK" auth ; pidgin_sipe_sso2.txt: using Auth = Auto). I'll add that "authfs1.launchpad.example.com" is my org's IDP. When I use the portal, that IDP successfully authenticates me.
