Sometimes when adding a UNIX namespace you can get the following message:
"CAFT Message: Transfer time limit exceeded UNIX NIS Directory"
Component: Identity Manager
The reason for this is a combination between the network and the fact that default protocol for CAM/CAFT is UDP.
Possible fix is to change the protocol on both the server and your clients to TCP.
On your server (where your IM C++ Connector Server is running):
camconfig *paths "<Your_Unix_endpoint_host_name> protocol=tcp" camsave persist
On your UNIX endpoint:
cd 'cat /etc/catngcampath'/bin ./camconfig *paths "<YOUR_SERVER_NAME> protocol=tcp" ./camsave persist
The above commands will switch CAM/CAFT communication to TCP port only between the specified Unix machine and IM CCS server machine. Other endpoints will not be affected.
