Re: How to store Newline character ?

[Himanshu <hshah0@sac.uky.edu>]

Sorry, It didn't work in openLDAP. Replacing '\n' by '$' to preserve the
original newline characters doesn't seem to work for me. I am not sure
whether I am doing some stupidity or it really doesn't work in openLDAP.
While doing ldapsearch, it shows the '$' sign and also after extracting
the data via C api, it shows $. Doesn't seem to treat $ as any special
character.
Any Clues ???


Thanks
