We have a very interesting automation/management challenge. We have a requirement to pull out a value from a LDAP server. We have currently implemented as below;

ExternalParameterShellExec=LdapQuery(*):/home/access/ldap.sh $1 $2 $3 $4

which in turn executes;

ldapsearch -P 2 -D Username -h $1 -w $2 -s sub "(objectclass=XXX)" -b "GUID=$3" -LL $4 | grep "$4" | sed "s/$4: //"

However it is deploying the DCI's to the nodes which I can not think of an effective way of doing. We would like a way of managing the TemplatedDCI and Thresholds globally but with local variables configured in the Node. The nodes are currently deployed in a template group which applies other DCI's. All the Nodes that the template is assigned against are networking equipment which can not run nxagentd. The volume of Nodes/DCI's that are needed to be created and maintained would make would make it infeasible to try and do manually.

The two approaches that I can think of doing this would be with a DCI like;
LdapQuery(GetCustomAttribute("ip"),GetCustomAttribute("user"),GetCustomAttribute("GUID"),GetCustomAttribute("value")) and having this run on the unit with the LdapQuery configuration set.

But this understandably it did not expect a nested function to be called.

Or alternatively run it as internal/Dummy and in the script get the CustomAttribute. However I am not sure of a way to call the LdapQuery function remotely.

Wondered if anyone else was aware of a different approach?
