Error 'Wrong signature' occurs while trying to add the remote node
When trying to add the remote node to the Enterprise Terminal Server, the following error occurs:
NX> 500 ERROR: Cannot add node '<node>:4000'. Wrong signature.
when PAM on the remote node is configured to block the nx user.
As a workaround, edit /usr/NX/etc/server.cfg on the remote node, uncomment (remove the pre-pending #) and set:
NXKeyBasedUsePAM 0
SOLVED, Released in version 6.9.2
