How do you feed a variable to an LDAP search to resolve account name to displayname?

I'm having an issue taking a search I have and feeding one of the results to an LDAP search to generate a new field that resolves the account name to the display name. Does anyone have any examples of how this can be done?

Below is an example of what i'm trying to do. This search results a field "user" which i want to use as the basis to search LDAP to resolve the displayname. However, i'm having some syntax errors

index=events EventCode = 8004 | eval displayname =  ldapsearch domain=test.local search="(objectClass=user)" attrs="displayName,sAMAccountName,userAccountControl" | where userAccountControl = "NORMAL_ACCOUNT" AND sAMAccountName =  "$user$"

I think i figured it out using ldapfilter instead of ldapsearch.
