Hello
If I do ipa user-mod test --user-auth-type=password --user-auth-type=otp I
have user:
[root at ipa-centos]# ipa user-show test
User login: test
First name: test
Last name: test
Home directory: /home/test
Login shell: /bin/sh
Principal name: test at MYDOMAIN.COM
Principal alias: test at MYDOMAIN.COM
Email address: test at mydomain.com
UID: 152200001
GID: 152200001
User authentication types: otp, password
Account disabled: False
Password: True
Member of groups: trust admins, ipausers, admins
Kerberos keys available: True
I can login into ipa-client.mydomain.com to ssh using password+otp token,
but for login to IPA Web UI I also need password+otp. I need just password
for IPA Web UI and password+otp token for ssh on ipa-client.mydomain.com.
[root at ipa-centos]# ipa service-show HTTP/
ipa-centos.mydomain.com at MYDOMAIN.COM --raw
