PHP ldap_add function to escape ldap special characters in DN syntax

Question

I\'m trying to add some users to my Ldap DB but I get some errors (invalid dn syntax) when I use some special characters like \",.\". I need a function that escape all chara

Answer 1

Those characters must escaped to be part of the data of a distinguished name or relative distinguished name. Escape the character (as in all LDAP) with a backslash 2 hex digit, such as \2a. Anything else would not be in compliance with the standards body documents. See RFC4514 for more specific information regarding the string representation of distinguished names.
