如何在 ldap 查询中转义特殊字符？

Question

I have one user on LDAP named with base DN

=CN=abc def\, ghi,CN=jkl,DC=mno,DC=pqr

and password is xyz .

I want to search this user in ldap, how do I do that? One thing is clear, the LDAP query should be like,

CN=abc def\\\, ghi\,CN=jkl\,DC=mno\,DC=pqr,xyz

tried these solutions

.getBindUserDN().replaceAll("[,]", "\\\\\\,").getBindUserDN().replaceAll(",", "\\,")

etc. What should be the logic here?

Answer 1

I found the solution but it's very much specific to this case where we specify only one backslash \\ and a comma , ie \\,

The problem was that, when I was trying to search for a ldap entry, I was taking the value of Bind DN directly. Later after trial and error method I understood that when I am searching for it's secret key we need 6 number of backslashes ie \\\\\\\\\\\\ to find it's secret key as LDAP store it with 3 backslashes and comma \\\\\\, .

But when I am going to look into Ldap for this secret key, so now I need to search with this new secret key, it means 6 backslashes should be there. So I have to search it with double the number of these backslashes ie 12 \\\\\\\\\\\\\\\\\\\\\\\\

PS:- This Solution appltes to a very particular case. But Logic should be similar if someone needs to apply it in a different way
