This issue appears to be identical to the one identified in https://bugzilla.redhat.com/show_bug.cgi?id=1347920 for RHEL 6

It seems it is fixable. I added some notes to the upstream bug report, however, I didn't have time to propose fix yet, sorry:

Comment 7 Ondrej Holy 2017-11-10 11:33:25 UTC
I proposed the following pull request:
which have been superseded by:
which will be hopefully merged upstream soon...

Comment 10 Ondrej Holy 2017-11-23 15:59:11 UTC
Just a note that FIPS encryption method is automatically used and NLA authentication is automatically disabled with this build if OpenSSL operates in FIPS mode. NLA can't be used, because FreeRDP implements only NTLM, which requires MD5, which isn't FIPS compliant.

Comment 12 Tomas Hudziec 2018-01-19 14:05:21 UTC
Have tested on x86_64 system running in FIPS mode with freerdp-1.0.2-13.el7.x86_64 and got mentioned error:
md4_dgst.c(75): OpenSSL internal error, assertion failed: Digest MD4 forbidden in FIPS mode!
Aborted (core dumped)

After update to freerdp-1.0.2-14.el7.x86_64 it works fine.
