Bug 1332709

*** Bug 1332725 has been marked as a duplicate of this bug. ***

RHEL Version
RHEL 7.3 x86_64 Server
 
DS Version
389-ds-base-1.3.5.3-1.el7.x86_64
389-ds-base-libs-1.3.5.3-1.el7.x86_64
 
Steps performed to verify
 
1. Created a standalone DS instance
 
2. Configured a global password policy as follows
 
[root@dell-per630-fc-04 ~]# ldapmodify -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: cn=config
changetype: modify
replace: passwordChange
passwordChange: on
-
replace: passwordHistory
passwordHistory: on
-
replace: passwordInHistory
passwordInHistory: 4
-
replace: passwordStorageScheme
passwordStorageScheme: CLEAR
modifying entry "cn=config"
 
3. Verified that the attributes are properly set
 
[root@dell-per630-fc-04 ~]# ldapsearch -xLLL -b 'cn=config' -h localhost -p 389 -D 'cn=Directory Manager' -w secret123 -s base passwordChange passwordHistory passwordInHistory passwordStorageScheme
dn: cn=config
passwordChange: on
passwordHistory: on
passwordInHistory: 4
passwordStorageScheme: CLEAR
 
 
4. Added a user entry as below
 
[root@dell-per630-fc-04 ~]# ldapadd -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: uid=tuser,ou=people,dc=example,dc=com
objectClass: top
objectClass: person
objectClass: inetorgperson
uid: tuser
cn: test user
sn: user
userpassword: secret123
adding new entry "uid=tuser,ou=people,dc=example,dc=com"
 
5. Modified user's password as Directory Manager as below
 
[root@dell-per630-fc-04 ~]# ldapmodify -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: uid=tuser,ou=people,dc=example,dc=com
changetype: modify
replace: userpassword
userpassword: secretpw1
modifying entry "uid=tuser,ou=people,dc=example,dc=com"
 
[root@dell-per630-fc-04 ~]# ldapmodify -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: uid=tuser,ou=people,dc=example,dc=com
changetype: modify
replace: userpassword
userpassword: secretpw2
modifying entry "uid=tuser,ou=people,dc=example,dc=com"
 
[root@dell-per630-fc-04 ~]# ldapmodify -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: uid=tuser,ou=people,dc=example,dc=com
changetype: modify
replace: userpassword
userpassword: secretpw3
modifying entry "uid=tuser,ou=people,dc=example,dc=com"
 
[root@dell-per630-fc-04 ~]# ldapmodify -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: uid=tuser,ou=people,dc=example,dc=com
changetype: modify
replace: userpassword
userpassword: secretpw4
modifying entry "uid=tuser,ou=people,dc=example,dc=com"
 
since the passwordInHistory attribute to a value of 4, I've changed the user's password 4 times
 
 
6. Tried binding to the server with old password to ensure that the password has been changed
 
[root@dell-per630-fc-04 ~]# ldapmodify -x -D 'uid=tuser,ou=people,dc=example,dc=com' -w secret123 -h localhost -p 389
ldap_bind: Invalid credentials (49)
 
as can be seen above, the bind fails with an invalid credentials error, this proves that the password has been changed successfully
 
7. Tried using the passwords again all 4 password again
 
[root@dell-per630-fc-04 ~]# ldapmodify -x -D 'uid=tuser,ou=people,dc=example,dc=com' -w secretpw4 -h localhost -p 389
dn: uid=tuser,ou=people,dc=example,dc=com
changetype: modify
replace: userpassword
userpassword: secretpw1
modifying entry "uid=tuser,ou=people,dc=example,dc=com"
ldap_modify: Constraint violation (19)
        additional info: password in history
 
 
[root@dell-per630-fc-04 ~]# ldapmodify -x -D 'uid=tuser,ou=people,dc=example,dc=com' -w secretpw4 -h localhost -p 389
dn: uid=tuser,ou=people,dc=example,dc=com
changetype: modify
replace: userpassword
userpassword: secretpw2
modifying entry "uid=tuser,ou=people,dc=example,dc=com"
ldap_modify: Constraint violation (19)
        additional info: password in history
 
[root@dell-per630-fc-04 ~]# ldapmodify -x -D 'uid=tuser,ou=people,dc=example,dc=com' -w secretpw4 -h localhost -p 389
dn: uid=tuser,ou=people,dc=example,dc=com
changetype: modify
replace: userpassword
userpassword: secretpw3
modifying entry "uid=tuser,ou=people,dc=example,dc=com"
ldap_modify: Constraint violation (19)
        additional info: password in history
 
[root@dell-per630-fc-04 ~]# ldapmodify -x -D 'uid=tuser,ou=people,dc=example,dc=com' -w secretpw4 -h localhost -p 389
dn: uid=tuser,ou=people,dc=example,dc=com
changetype: modify
replace: userpassword
userpassword: secretpw4
modifying entry "uid=tuser,ou=people,dc=example,dc=com"
ldap_modify: Constraint violation (19)
        additional info: password in history
 
 
as can be seen above, all 4 passwords are rejected as all of them are stored in history
 
8. Tried using a different password
 
[root@dell-per630-fc-04 ~]# ldapmodify -x -D 'uid=tuser,ou=people,dc=example,dc=com' -w secretpw4 -h localhost -p 389
dn: uid=tuser,ou=people,dc=example,dc=com
changetype: modify
replace: userpassword
userpassword: secret1234
modifying entry "uid=tuser,ou=people,dc=example,dc=com"
 
as can be seen above, this password is accepted and saved since it is different

Would it be possible to backport this fix to RHEL6?
