(ITS#4926) german special characters ( Umlaute ) in Password
by m.birkenkamp＠e-fact-gmbh.de 13 Apr '07

13 Apr '07

Full_Name: Marcel Birkenkamp Version: 2.1.22 OS: HP-UX 11.11 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (84.63.14.237) hi, i have a problem submitting passwords containing german special characters (Umlaute ä,ü,ö & ß) by using the OpenLDAP Function ldap_simple_bind_s to our Active Directory Server. After investigating the issue it seems as if the password is cut off at the position of the special char, since it is possible to log in a user with his password (without special characters) if i use the correct password and add one of these characters to the end. Example: password for user: test submitted: testö this would succeed the problem is if a user i.e. enters the password: bäume the submitted password is: b Is there a fix/workaround for this? btw: i'm using this in a c program. Thanks in advance.

OK, I completely screwed the thing. slapd-search doesn't do anything about referrals, so it sticks with the default of libldap (on); also, it seems to have no -C flag. I'll fix this in a moment. This leaves the open point of ldap_result() returning what appears to be LDAP_REQ_BIND instead of a LDAP_RES_* in response to ... LDAP_REQ_BIND itself. Still digging... p. Ing.

It's not back-ldap that's trying to chase referrals here. It's slapd-search (from the tester binaries), but if I see it corretcly that has referral chasing turned of as well. At least it is not started with the -C option, which should enable referral chasing. That's indeed puzzling. -- Ralf

I checked back to 2.3.27 and the problem as present there as well. I was however not yet able to reproduce the issue on another architecture, I've been running test039 for a few hours on an Intel x86_64 box without any problem. So this problem might as well be locate in some other part of the system (kernel, glibc, ...). What do you think? -- Ralf

Yes, I had that on my list already. I am also trying to reproduce it on a different architecture, currently I only used different PowerPC machines. -- Ralf
