Hi,

Do you have any idea how to parse LDAP filters (Which is prefix by
nature) to infix expression? We need this in our project. Any help will
be appreciated.



Thank you,

Atanu Mandal

> Current version of the Filter parser was implemented with the Antlr Selector trick and is now hard to maintain. As it's a bit complex code I could not easily modify it to fix some possible reentrance problems. We need to implement a new LDAP filter, possibly by hand, in order to be able to maintain it and avoid untrackable problems.
