[exim] Help troubleshooting router error

I have this roiuter defined to do a ldap lookup for dynamic groups but it
gives a error. Can someone maybe help me tofind out why?


Carinus

group_aliases:
  driver = redirect
  allow_fail
  allow_defer
  data = ${lookup ldap {ldap://ldap.domain.com/\
    o=people,o=base?mgrpdeliverto?sub?\

(|(mail=$local_part@$domain)(mailAlternateAddress=$local_part@$domain))}{$value}fail}
condition = ${if match {$local_part}{extract{mail}{$address_data}}}
# user = exim
file_transport = address_file
pipe_transport = address_pipe


group@??? cannot be resolved at this time:
error in redirect data: missing or malformed local part (expected word
or "<") in "ldap://ldap.domain.com/o=base"
