Hi All,

I have an openldap server which authenticates users. The search gives a success
for some speacial characters in the filter.

Eg:
ldapsearch -b "o=xyz" "(uid=test)"
ldapsearch -b "o=xyz" "(uid=\test)"

Both these queries returns success.

Can we some how disable this and disallow characters like  "*()\"  etc on the
filter.

Thanks in advance
Susanth
