SED +ldif

[asmar]

Hello all,

I have an export from an OpenLDAP directory and want to modify all users to accommodate a new scheme.

Example user.ldif is:

dn: cn=Firstname Lastname,ou=Users,dc=bca,dc=edu,dc=gr
objectClass: inetOrgPerson
objectClass: posixAccount
objectClass: person
objectClass: organizationalPerson
objectClass: top
givenName: Firstname
sn: Lastname
cn: Firstname Lastname
uid: flastname
userPassword: {CRYPT}dfdfsdf2lRBeF.
uidNumber: 1029
gidNumber: 100
homeDirectory: /home/flastname
loginShell: /bin/false
mail: flastname@mydomain.com

What I need is to replace the cn=Firstname Lastname with uid=flastname in the whole file where ofcourse the value of Firstname Lastname changes per user.

This needs to be done in the whole file (many users). Is there a way with SED to achieve this in order to avoid editing the fil by hand?

I'm pretty sure this could be done with sed, but it would be much easier to do it with awk or perl (or even bash).
