Perl one liner to remove a line that carries over to another new line which starts with a space

I need a perl one liner, I need to remove some fields from a ldap dump to give to Sun for some troubleshooting, the problem I have is I can remove the lines I need but not everything. The way the ldap records work is if there is a line that carries over to another line there is a space at the first of the line which tell ldap that it is one line.

The ldap dump I have is now just a text file but if I remove the lines I need it does not remove the rest of the line on the attributes I'm removing if there is a carry over to a new line.

Example:

In this part of a example I'm I need to remove the homePostalAddress: which if I remove it a few ways that I know how I just remove the line of homePostalAddress: 65 Millfield Lane,  Nether Poppleton,  York,  YO26 6NB,  Un, but the continuation of that attribute is carried over to the next line so the ( ited Kingdom,) is not removed.

I'm trying to find a perl one liner where it would make the above example come out to be:


dn: cn=John Doe  100397,ou=employee,o=abc,c=ou
modifyTimestamp: 20080308162306Z
modifiersName: cn=John Doe 100397,ou=employee,o=abc,c=ou
