The 4.x Tectia Server is no longer supported. To see the list of currently supported products, please see: http://www.tectia.com/en/Support/Support_Services/End_of_Support_Dates.iw3

To answer your question:

In certain circumstances starting ssh-certd fails with fatal error "Could not open listener for the validation server". To resolve the issue, remove the existing listener socket file manually.

for example when ssh-certd process is unexpectedly or forcefully terminated, the validation server's listener socket file may not get removed automatically. Consequently attempts to (re)start ssh-certd will produce error message like:

# /etc/init.d/ssh-certd start
Starting ssh-certd: ssh-certd[829]: WARNING: Can not bind local address /var/run/ssh-certd-listener: Address already in use
ssh-certd[829]: FATAL: Could not open listener for the validation server
