Hi!
Update: Today when I reloaded the config and re-applied the LDIFs, it worked!
I guess slapd had corrupted the config database in some strange way.

Kind regards,

Hi!



Even after having opened a support case with SUSE, it took about two weeks 
until I got any further:

Essentially you cannot add the values to "olcDatabase={-1}frontend,cn=config", 
but only to "cn=config".

However after that I got a new message when trying to change a user's password:


Result: Constraint violation (19)

Additional info: Password policy only allows one password value



At that time I had two values assigned, but even after assigning only one 
value, the message did not change.



Even more, slapd suddenly had exited and refused to restart with the messages:

slapd[13769]: olcPasswordHash: value #0: <olcPasswordHash> scheme not available 
({SSHA256})

slapd[13769]: olcPasswordHash: value #0: <olcPasswordHash> no valid hashes found

slapd[13769]: config error processing cn=config: <olcPasswordHash> no valid 
hashes found

...

slapd[13769]: slapd stopped.





Changes actually applied were:

dn: cn=module{0},cn=config

changetype: modify

add: olcModuleLoad

olcModuleLoad: {4}pw-sha2.so



dn: cn=config

changetype: modify

replace: olcPasswordHash

olcPasswordHash: {SSHA256}



Any ideas?



Kind regards,

Hi!

After having loaded pw-sha2 in oOpenmLDAp 2.5, I tried to set a new default 
hashing schema, but I fail to do so using

dn: olcDatabase={-1}frontend,cn=config
changetype: modify
add: olcPasswordHash
olcPasswordHash: {SSHA256}
olcPasswordHash: {SSHA}

----
modifying entry "olcDatabase={-1}frontend,cn=config"
ldap_modify: Object class violation (65)
        additional info: attribute 'olcPasswordHash' not allowed

Before I had tried "replace" instead of "add", and I tried to place both values 
in one line as suggested by slapd-config:
       olcPasswordHash: <hash> [<hash>...]
              This option  configures  one  or  more  hashes  to  be  used  in
              generation   of   user  passwords  stored  in  the  userPassword
              attribute during processing of  LDAP  Password  Modify  Extended
              Operations (RFC 3062).  The <hash> must be one of {SSHA}, {SHA},
              {SMD5}, {MD5}, {CRYPT}, and {CLEARTEXT}.  The default is {SSHA}.

The manual page also states:
This setting is only allowed in the frontend entry.

I'm running out of ideas.

Kind regards,
Ulrich Windl
