[Impact] * In a multi-domain environment setup with LDAP or IPA, the username is not parsed correctly, resulting in id mapping issues.
* As a result, NFSv4 cannot be used in a multi-domain environment at all if the username is of the form user@authentication_domain@idmap_domain * The attached patch fixes an almost 10 year old bug in the libnfsidmap library. The patch is included already in a similar form in current RHEL releases. [Test Case] * IPA with 2 different user domains. For example: user1@domain1 and user2@domain2. * NFSv4 server enrolled into IPA * NFS client enrolled into IPA. User and group names coming from IPA have an '@' in them. [Regression Potential] * The attached patch has been in production in a major organisation with more than 500 Ubuntu clients for more than a year now and has not shown any issues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1728310 Title: libnfsidmap2 fails to obtain username which results in failed translation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libnfsidmap/+bug/1728310/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
