[Freeipa-users] ERROR: CIFS server communication error: Memory allocation error (both may be "None") upon establishing trust

Hi all, I have been trying to set up one-way trust for quite a while. I thought I have everything sorted out but when I tried to move from test environment to production, I received error below upon trying to set up trust with ipa trust add: ipa trust-add --type=ad my.domain.com --admin adminaccount --password ipa: ERROR: CIFS server communication error: code "-1073741801", message "Memory allocation error" (both may be "None") Googling returned some results that suggested upgrading samba and freeipa versions. I did so and now I am using: freeipa - 4.5.3-1.fc26 samba - 2:4.6.7-0.fc26 This however didn't change the result. What can be important here is that my.domain.com is a child domain of domain.com in terms of AD (it is a separate domain controller). Can you please advise how to fix it?
