|

# This script is used to adapt the charset in an egw ldap addressbook *
|
|
||||||
# to the egw code in Release 1.1 and newer. *
|
|
||||||
# *
|
|
||||||
# *
|
|
||||||
# The old egw code just called utf8_encode on every attribute before *
|
|
||||||
# writing and utf8_decode after reading an ldap attribute. This was *
|
|
||||||
# fine as long as egw was run in iso8859-1, because then, calling *
|
|
||||||
# utf8_encode was a proper conversion. *
|
|
||||||
# But since egw supported systemcharsets, this call led to strings *
|
|
||||||
# being encoded _twice_ before they were sent to ldap and thus being *
|
|
||||||
# encoded in some weired mix of 2 charsets. *
|
|
||||||
# This of course confuses other LDAP-clients, because they don't *
|
|
||||||
# know about the actual charset of the data anymore. *
|
|
||||||
# The new egw code now correctly _converts_ from every charset to utf8 *
|
|
||||||
# before sending data to ldap and converts from utf8 to systemcharset *
|
|
||||||
# on reading. This of course makes it necessary, to correct the charset *
|
|
||||||
# of existing entries in the ldap-branch used by egw-addressbook *
|
|
||||||
# (i.e. really make them utf-8), before the new code is being used. *
|
|
||||||
# *
|
|
||||||
# How to use this script: *
|
|
||||||
# 1. make a datadump of your ldap database (f.e. slapcat>data.ldif) *
|
|
||||||
# 2. configure this script below *
|
|
||||||
# 3. convert the dump (./fix-ldap-charset-for-egw1.1.pl data.ldif) *
|
|
||||||
# 4. reimport the dump (f.e. slapadd -l data.ldif.conv) *
|
|
||||||
