Hello. In our system we have been tracking the data for correctness for a long time and this work is hard to do if we don't keep operation history, e.g. which operator changed the contact information of which person on what date.
Basically what we need is simply the possibility to keep all
modifytimestampe and modifiersname for all the time. The two attributes
values are replaced each time an operator make modification, thus we no
longer know who made modification before him or her.
If LDAP server can be adjusted to behave this way: each time an operator
make modification, instead of replace values for modifytimestampe and
modifiersname, a new value is simply added. so if the entry is modified
10 times, both modifiersname and modifytimestampe should have 10 values.
Now what could be the best way to keep these data? I think I have these
ideas:
1. keep a log file in /var/log/, write modifytimestampe and
modifiersname into this file as well as dn of the entry being
edited, before write operation is done. The downside is we need
to modify ldap client source code, and it's difficult to collect
these logs to analyse them;
2. modify ldap client source code, add one customized attribute
e.g. "modifiersnames" and "modifytimestamps" which is used in
this way: copy value of modifiersname and modifytimestampe and
add them to "modifiersnames" and "modifytimestamps". this
require re-configure LDAP server too, to include these special
attributes;
3. modify source code of LDAP server, to make it maintain
modifiersname and modifytimestampe in the way that old values
are not discarded. This require no modification on existing
applications (LDAP clients) but is difficult to do (LDAP server
require more knowledge to work on) and perhaps violate the RFC
that defined modifiersname and modifytimestampe
which approach you would suggest to take? Thank you in advance for
suggestions!
