I have in my ldifs, whatever the way I do them (slapcat ldapsearch

Here is a sample:
nisMapEntry::

Which should be:
nisMapEntry: -rw,tcp,intr,rsize=32768,wsize=32768,timeo=50,retrans=10
yak20:/usr2/users/&

In LDIF syntax :: behind the attribute type name indicates that the
attribute
value is base64-encoded (see RFC 2849).

$ python -c "print
'LXJ3LHRjcCxpbnRyLHJzaXplPTMyNzY4LHdzaXplPTMyNzY4LHRpbWVvPTUwLHJldHJhbnM9MTAgeWFrMjA6L3VzcjIvdXNlcnMvJiA='.decode('base64')"

-rw,tcp,intr,rsize=32768,wsize=32768,timeo=50,retrans=10
yak20:/usr2/users/&

Ciao, Michael.

Thank you for that piece of code, but, any idea why it's bas64 encoded ?
As I've been told:
"If an attribute contains non-printing characters or begins with a
space, a colon or a less than (<) the value will be base64 encoded.
Your NIS entries might have an extra white space in the generated
LDIF."
But with those two entries, which looks to me "exactly" the same, once
sorted with a slapcat, store12's one is base64 encoded while store11's
one isn't.

Merci.

OK, I have some lines ending by space.
As RFC2849 says:
Values or distinguished names that end with SPACE SHOULD be base-64 encoded.

Thanks for your help
