Red Hat Directory Server - Escape special characters

ldap filter escape parentheses
vbscript escape backslash
ldap character
ldap filter spaces
powershell escape greater than sign
vbscript escape character

I am getting error "Error while performing search ERR_04149 Not a valid escaped value" when running the following search query against Red Hat Directory Server:

cn=cn\3DnsPwPolicyEntry\,ou\3Dinternal\,o\3Dcompany\,c\3Dgr,cn=nsPwPolicyContainer,ou=internal,o=company,c=gr

Any ideas on how to escape characters properly?

According to the LDAP wiki, the characters that need escaping are:

comma , Backslash character \ Pound sign (hash sign) # Plus sign + Less than symbol < Greater than symbol > Semicolon ; Double quote (quotation mark) " Equal sign = Leading or trailing spaces

It looks like you're trying to escape numbers, which do not need to be escaped.

Also, the following characters don't need to be escaped either:

* ( ) . & - _ [ ] ` ~ | @ $ % ^ ? : { } ! '

C.2. Escaping Unsafe Characters Red Hat Directory Server 11, Escaping Unsafe Characters. Any unsafe characters in the URL need to be escaped, or substituted with a special sequence of characters.

cn=cn\3DnsPwPolicyEntry\,ou\3Dinternal\,o\3Dcompany\,c\3Dgr,cn=nsPwPolicyContainer,ou=internal,o=company,c=gr

This looks bogus to me because this RDN value looks like you've escaped all equal signs with the byte-encoding:

cn\3DnsPwPolicyEntry\,ou\3Dinternal\,o\3Dcompany\,c\3Dgr

You would have to also escape the comma if you really want to use that value. I'm pretty sure one usually don't add entries with such an RDN beneath cn=nsPwPolicyContainer,ou=internal,o=company,c=gr. There seems to be another issue in whatever code you're using.

To avoid such issues without having to dive into RFC 4514 I strongly recommend to use a decent LDAP module package for your favourite programming language with decent quoting functions and not roll your own home-grown script.

  • Actually what I am trying to do is to perform an LDAP lookup on this DN: cn=cn\3DnsPwPolicyEntry\,ou\3Dinternal\,o\3Dcompany\,c\3Dgr,cn=nsPwPolicyContainer,ou=internal,o=company,c=gr .Although I can verify the existence of this D.N. every time I open the Apache Directory Studio, I cannot search for it and I am failing to make a successful LDAP query in Java.
