Our setup on server side is that we have two root like users with same UID. Password authentification did not work because authentication was taken for user root instead of user aroot. As I changed the sequence in /etc/passwd it worked (having aroot before root).
#########################################################
Excerpt from /etc/passwd:
root:x:0:0:root:/root:/bin/bash
…
aroot:x:0:0::/root:/bin/bash
…
nx:x:480:1007::/var/NX/nx:/etc/NX/nxserverIf I try to login with the lroot user, nxserver tries to authenticate with the root credentials (see DEBUG log below).
When I change the sequence of root and aroot, it works:
aroot:x:0:0::/root:/bin/bash
…
root:x:0:0:root:/root:/bin/bash
