Search is waiting for input message caused by ldapsearch?

[wnyricsplunk]

I have created a dashboard which shows print jobs by Print Server/Printer/Time. I would like to include the actual name of the user instead of the sAMAccountName. I have added an ldapsearch to a "one-off" query and that works the way I expect.

sourcetype=xmlwineventlog EventCode=307 Computer="fqdnOfPrintServer" | fields UserData_Xml,ThreadID | xmlkv | eval Document=Param2,UserName=Param3,Workstation=Param4,Printer=Param5,IPAddress=Param6,Bytes=Param7,Pages=Param8 | search Printer=* | join type=inner Computer,ThreadID [search sourcetype=xmlwineventlog EventCode=805 | fields UserData_Xml,ThreadID | xmlkv | eval Copies=Copies] | eval TotalPages = Pages * Copies | ldapfilter search="(&(objectclass=user)(!(objectclass=computer))(samAccountName=$UserName$))" attrs="displayName" | table _time,displayName,Printer,Document,Workstation,Pages,Copies,TotalPages

When I put this query into my dashboard and substitute the tokens $host$ for the Print Server and $Printer$ for the printer name, I get a "search is waiting for input" message. From what I have read, this usually means an issue with a token. When I remove the ldapsearch part of the query it works fine but displays only the sAMAccountName. Is the issue the $Username$ token in the ldapsearch? I have tried removing the $ before and after UserName but then the search displays "No results found". Is there a way to mofify this to get the information I want?

@wnyricsplunk,

Try escaping the $ with $$

ie.

samAccountName=$$UserName$$

[wnyricsplunk]

That did it! Thank you!!

Good. So it was the combination of @renjith.nair his suggestion and mine that solved it? I've converted his comment to an answer, so you can mark it as accepted.

It did change from waiting for input but now there are no results found.

why do you use $$ for the host and printer tokens? That should be single $. Try it with single $ signs.
