Trivino 2022-09-21 10:30:04 UTC Doc Text Cause:
RC4 (NTLM hash) is not allowed in FIPS mode.

Consequence:
two-way trust can't be established in FIPS mode.

Workaround (if any):

Result:
when establishing two-way trust, Win AD-DC attempts to auth to IPA DC by using NTLMSSP which is blocked by FIPS, communication fallsdown to "gse_krb5" which is not working and needs to be investigated as part of this BZ.

.IdM in FIPS mode does not support using the NTLMSSP protocol to establish a two-way cross-forest trust

Establishing a two-way cross-forest trust between Active Directory (AD) and Identity Management (IdM) with FIPS mode enabled fails because the New Technology LAN Manager Security Support Provider (NTLMSSP) authentication is not FIPS-compliant. IdM in FIPS mode does not accept the RC4 NTLM hash that the AD domain controller uses when attempting to authenticate.
