First, thank you for your help. It saves me a lot of time. And I hope
that I'll document the whole procedure for the others. One important
general question. Are there any changes in FreeIPA 2 that will
invalidate all this procedure?
Back to the main problem, I removed the entries for DNA that were in a
wrong place and after adding DNA configuration for sambaSID in
cn=ipa-dna,cn=plugins,cn=config I can now add users. All the samba
related attributes are added to a new user after I set initial password.
But I can not login using smbclient because samba thinks that the
password is expired. Either I have to set X in samba flags (password
never expires) or I have to properly initialize password related fields
for samba. Setting password fields would be preferable, is it possible
and how?
Easier way (and necessary in case of groups) is to set fixed value when
creating new users and groups. The question is, is it possible to
configure DNA plugin to set fixed value, or there is specialized (or
more appropriate) plugin for that?
