Ldapsearch filter on DN component

Hello All,

I am trying to write a program with some logical filters. I am not sure if
the syntax is wrong or the logic itself.

$mesg = $ldap->search( base => dc=domain,dc=com, filter =>
(&(&(uid=test)(ou:dn:=People))(&(cn=test)(ou:dn:=Group))), attr => ³*²)

Error: Bad filter

HELP: Can you verify if my filter is right? Also suggest alternate filter
you think might solve the purpose.

What I am trying to do?
For a given uid=test, check if the posixAccount exists in ou=people and also
check if the corresponding group is also present in ou=Group.
Return true when both user and group exists for uid=test. Else false.

Why so complex? Because the user accounts also have CN value which is
Firstname Lastname and it should not be checked against.


Thanks,
Prashanth
