Re: basic login fails : here are some logs ...



I have problem to use my openldap 2.4 server for authentication on a fedora 14 :
it sounds that the problem is on the on the client side configuration.

Here are some logs : your help to diag would be appreciated.

-> I have an ldap server that that stores posixAccount and respond to
ldap queries.
-> I have configure a client machine to use this ldap server for
authentication when login :

***** LOGS ***

**** CLIENT side ****

 login: olivier
 passe :

 Login incorrect

**** SERVER when login on the client ***

Here is what I see on the server side (IP=10.1.92.24) when I try to log in as
"olivier" on the client (10.1.86.93) using /bin/login (debug level 256) :

conn=1220 fd=13 ACCEPT from IP=10.1.86.93:54458 (IP=10.1.92.24:389)
conn=1220 op=0 BIND dn="" method=128
conn=1220 op=0 RESULT tag=97 err=0 text=
conn=1220 op=1 SRCH base="ou=People,ou=staff,dc=mydomain,dc=fr"
scope=2 deref=0 filter="(uid=olivier)"

shadowWarning uidNumber
conn=1220 op=1 SEARCH RESULT tag=101 err=32 nentries=0 text=




*** CLIENT When using ldappasswd *****

I manage to change the "userPassword" attributes using ldappasswd command, here
are the logs on the client and server side :

Client side :

$ ldapsearch -h ldap-master1.mydomain.fr -D
"cn=Manager,dc=mydomain,dc=fr" -w secret "uid=olivier"

 dn: uid=olivier,ou=Staff,ou=People,dc=mydomain,dc=fr
 uid: olivier
...
objectClass: account
objectClass: posixAccount
objectClass: top
userPassword:: e1NTSEF9UmlYdnk4MWtaZ0NMS2hyZnBvd2hlaezrbTd7aR5LU0s=

$ ldappasswd -h -h ldap-master1.mydomain.fr -D
"cn=Manager,dc=mydomain,dc=fr" -w secret
"uid=olivier,ou=Staff,ou=People,dc=mydomain,dc=fr" -s newpass

$ ldapsearch -h ldap-master1.mydomain.fr -D
"cn=Manager,dc=mydomain,dc=fr" -w secret "uid=olivier"

 dn: uid=olivier,ou=Staff,ou=People,dc=mydomain,dc=fr
 uid: olivier
...
objectClass: account
objectClass: posixAccount
objectClass: top
userPassword:: e1NTSEF9UmlYdnk4MWtaZ0NMS2hyZnBvd2hlaezrbTd7aR5LU0s=

*** SERVER side When using ldappasswd *****

Server side, here are the logs related to ldapppasswd  :

conn=1000 fd=11 ACCEPT from IP=10.1.86.93:52074 (IP=10.1.92.24:389)
conn=1000 op=0 BIND dn="cn=Manager,dc=mydomain,dc=fr" method=128
conn=1000 op=0 BIND dn="cn=Manager,dc=mydomain,dc=fr" mech=SIMPLE ssf=0
