adding a new CN if i use UPPERCASE UTF-8 character server respond "does not such object". if i use lowercase there is no problem. just for UPPERCASE UTF-8 i found this problem after fc12 t fc13 upgrade. But, i made a clean install and migrate all old directory from ldif file. The problem still continue. This is interesting. Because my ldif file has lots of UTF-8 CNs. while i was importing them didn't see any problems. log example; [01/Oct/2010:11:24:29 +0300] conn=47903 op=1 SRCH base="CN=H\c3\9cSEY\c4\b0N CANTA\c5\9e,ou=TMO_GNMUD_BILGII_SLEM_DAIRE_BSK,o=TARIM_VE_KOYISLERI_BAKANLIGI,o=KAMU_KURUMLARI,o=NES,o=SERTIFIKA,C=TR" scope=0 filter="(cn=H\c3\9cSEY\c4\b0N CANTA\c5\9e)" attrs=ALL [01/Oct/2010:11:24:29 +0300] conn=47903 op=1 RESULT err=32 tag=101 nentries=0 etime=0 [01/Oct/2010:11:24:29 +0300] conn=47903 op=2 SRCH base="CN=H\c3\9cSEY\c4\b0N CANTA\c5\9e-1344529107,ou=TMO_GNMUD_BILGII_SLEM_DAIRE_BSK,o=TARIM_VE_KOYISLERI_BAKANLIGI,o=KAMU_KURUMLARI,o=NES,o=SERTIFIKA,C=TR" scope=0 filter="(cn=H\c3\9cSEY\c4\b0N CANTA\c5\9e-1344529107)" attrs=ALL [01/Oct/2010:11:24:29 +0300] conn=47903 op=2 RESULT err=32 tag=101 nentries=0 etime=0

Created attachment 451562 [details] git patch file (master) Description: There was a bug in the utf8 uppe2Lower table: Character İ (LATIN CAPITAL LETTER I WITH DOT ABOVE) did not map to the corresponding LATIN SMALL LETTER DOTLESS I (2 bytes) but to ascii 'i' (1 byte). The shortened DN tailed with a garbage character and the entry was treated as an orphan entry which does not belong to any suffix. This patch fixes the mapping table mismatch as well as adds a code to dn_ignore_case_to_end to force to NULL terminate the converted string. Files: ldap/servers/slapd/dn.c ldap/servers/slapd/utf8compare.c
Thank you so much. it's working. I hope i'll be included next release.

can you please add steps to reproduce and verify thanks
Create an entry including the character in dn: Character İ (LATIN CAPITAL LETTER I WITH DOT ABOVE) e.g., dn: cn=İ, dc=example,dc=com cn: İ ... Add the entry, then search the entry with the filter "(cn=İ)" as well as "(cn=ı)" <== corresponding LATIN SMALL LETTER DOTLESS I (2 bytes) The search should return the entry. Also, search with the filter "(cn=i)" <== ascii 'i'. This search should NOT return the entry. If the above searches work as expected, this bug is verified.

One of the "features" of ldapsearch is that it will base64 encode non-printable values, such as strings which contain 8-bit characters. python >>> import base64 >>> base64.b64decode('dWlkPcSwLGRjPWV4YW1wbGUsZGM9Y29t') 'uid=\xc4\xb0,dc=example,dc=com' >>> base64.b64decode('xLA=') '\xc4\xb0' I believe \xc4\xb0 is the utf-8 encoding of ı > > 2.

ok, that said I am marking the bug as VERIFIED.
