Fixed upstream: master: https://fedorahosted.org/freeipa/changeset/a1430dcb2c8e63e3077d00878431c0698944a07d ipa-2-1: https://fedorahosted.org/freeipa/changeset/fb6abb2acc190d1c397f9e4e170c03bfcd39048d
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: Cause: When a new user is added, its login is normalized and put to lower-case. However, its principal is not normalized and contains original login Consequence: If user adds a new user with uppercase letter in its login, a disconnect between a user login and his principal is created. IPA server then refuses to create a password for that user Fix: Normalize both new user login and his principal Result: When a new user with upper-case letter in his login is added, both login and principal are normalized and put to lower-case. IPA server is then able to create a Kerberos password for the user.
