Public bug reported:
Problem:
getent passwd lists a /etc/passwd like list of known users. If there are
active directory users you may get an output like that:
AUTH\short#1234567.net:*:3000123:100:short#1234567.net:/home/AUTH/short#1234567.net:/bin/false
AUTH\longername#1234567.ne:*:3000124:100:longername#1234567.net:/home/AUTH/longername#1234567.ne:/bin/false
At "longername" may should notice the truncation of TLD name .net to .ne
There are more issues arising from that, e.g.
su - longername#1234567.ne work, but su - longername#1234567.net does not work.
Expected behavior:
getent passwd should display:
AUTH\short#1234567.net:*:3000123:100:short#1234567.net:/home/AUTH/short#1234567.net:/bin/false
AUTH\longername#1234567.net:*:3000124:100:longername#1234567.net:/home/AUTH/longername#1234567.net:/bin/false
