entryrdn-index error message in error log
Hi Andrey,
Looking at this line, ', is not a UTF-8 representation of
apostrophe. Rather a Latin-1 representation? Also, it contains ',' in
the rdn value without an escape. It's considered a separator between
rdns. I wonder who created the input DN...?

Thanks, Rich! You are right! And I don't think our DN normalizer
supports it.
Andrey, what you observe is ...
389 v1.2.6.rc7 has no problem to handle cn=salon d',honneur, but
1.2.7.a1 does?
We haven't touched the normalizer between 1.2.6.rc7 and 1.2.7.a1, I think...

entryrdn-index error message in error log
Well, i've sorted out this problem. Rich has pointed out that it's an html/xml escape. He was right. Since i was working on our production servers there were some requests constantly coming in. I've searched through the access logs and found that the source of the problem is a broken web application *that requests an incorrect DN :
[25/Aug/2010:21:25:21 +0200] conn=4201 op=1 RESULT err=32 tag=101 nentries=0 etime=0.002000
These requests generate the messages i've seen in error log :
[25/Aug/2010:21:25:21 +0200] entryrdn-index - entryrdn_index_read: Param error: Failed to convert cn=cadre d',astreinte,ou=objets,dc=id,dc=polytechnique,dc =edu to Slapi_RDN
[25/Aug/2010:21:25:21 +0200] - dn2entry: Failed to get id for cn=cadre d',astreinte,ou=objets,dc=id,dc=polytechnique,dc =edu from entryrdn index (34)
[25/Aug/2010:21:25:21 +0200] entryrdn-index - entryrdn_index_read: Param error: Failed to convert astreinte,ou=objets,dc=id,dc=polytechnique,dc=edu to Slapi_RDN
So there is no problem in the server code, it's a broken application. It applies to both 6rc7 *and 7rc1 versions of course. The reason why i thought there was no problem in rc7 case is that i've made the tests with rc7 at 21h00, at this time there were no users and so no requests from the above-mentioned application )
I was alarmed because*on our servers there are very few error messages in error logs and i know them all. This sort of error message (incorrect DN or filter in ldap search requests) was not logged in previous 389 versions, it's a behavour change...*
So the only thing that i should look into is the server crash during SSL incremental replication in the current git version.

Thank you so much for the update, Andrey.* You eliminated one of our
concerns!* (Of course, there are plenty more.

*that requests an incorrect DN :
[25/Aug/2010:21:25:21 +0200] conn=4201 op=1 RESULT err=32 tag=101
nentries=0 etime=0.002000
These requests generate the messages i've seen in error log :
[25/Aug/2010:21:25:21 +0200] entryrdn-index - entryrdn_index_read:
Param error: Failed to convert cn=cadre

d',astreinte,ou=objets,dc=id,dc=polytechnique,dc =edu from
entryrdn index (34)

Param error: Failed to convert
astreinte,ou=objets,dc=id,dc=polytechnique,dc=edu to Slapi_RDN
So there is no problem in the server code, it's a broken
application. It applies to both 6rc7 *and 7rc1 versions of course.
The reason why i thought there was no problem in rc7 case is that
i've made the tests with rc7 at 21h00, at this time there were no
users and so no requests from the above-mentioned application )
I was alarmed because*on our servers there are very few error
messages in error logs and i know them all. This sort of error
message (incorrect DN or filter in ldap search requests) was not
logged in previous 389 versions, it's a behavour change...*
So the only thing that i should look into is the server crash
during SSL incremental replication in the current git version.

Are there any other issues with 1.2.6.rc7? If not, I would like to tag
this as the final 1.2.6 and push it to stable.
