Didn't anyone experience "weird things" with ldap authentication? Like:
- password mismatch that get solved by restarting apache
- password error, wait 10 minutes, relogin (with same username/password)
and you can enter
Any help and suggestion is appreciate, this is really critical for us
and we can't find any clear information about it.
Regards,
Sandro

Hello,
we've migrated part of our apache auth to LDAP, but suddenly we receive
errors like "Password Mismatch" while the user's password is correct.
In the log we can read:
[Wed Dec 02 17:42:54 2009] [warn] [client <IP ADDRESS>] [3659] auth_ldap
authenticate: user <user> authentication failed; URI /
[ldap_simple_bind_s() to check user credentials failed][Invalid credentials]
[Wed Dec 02 17:42:54 2009] [error] [client <IP ADDRESS>]] user <user>:
authentication failure for "/": Password Mismatch
but if we use ldapsearch command to bind to the ldap servers, with the
very same username & password the user can login successfully.
The httpd.conf ldap relevant entries are:
# grep -i ldap /usr/local/apache/conf/httpd.conf
LoadModule ldap_module modules/mod_ldap.so
LoadModule authnz_ldap_module modules/mod_authnz_ldap.so
LDAPVerifyServerCert Off
LDAPTrustedMode STARTTLS
LDAPSharedCacheSize 200000
LDAPCacheEntries 1024
LDAPCacheTTL 600
LDAPOpCacheEntries 1024
LDAPOpCacheTTL 600
while the .htaccess we use is:
AuthType Basic
AuthName "<name>"
AuthBasicProvider ldap
AuthzLDAPAuthoritative Off
AuthLDAPBindDN <uid for bind>
AuthLDAPBindPassword <pwd>
AuthLDAPURL ldaps://<server>/dc=ABC,dc=DEF?uid?sub?(objectClass=*)
require ldap-group <CN for the auth group>
The password mismatch for a user usually goes away after apache is
restarted, but then other users (that were able to login before restart)
start facing the login incorrect.
Could you please suggest what to do to resolve this really annoying problem?
Thanks in advance,
Sandro
