I have the directive

pam_password exop

in /etc/ldap.conf. Hope this is enough (but doesn't work anyway).

When I debug slapd (with -d 128) while trying to change the password I see:

slap_global_control: unrecognized control: 1.3.6.1.4.1.42.2.27.8.5.1
=> access_allowed: result not in cache (userPassword)
=> access_allowed: auth access to "uid=vp,ou=People,dc=teraphim,dc=de" 
"userPassword" requested
=> slap_access_allowed: backend default auth access granted to "(anonymous)"
=> access_allowed: auth access granted by read(=rscxd)
slap_global_control: unrecognized control: 1.3.6.1.4.1.42.2.27.8.5.1
=> bdb_entry_get: found entry: "uid=vp,ou=people,dc=teraphim,dc=de"
=> access_allowed: result not in cache (userPassword)
=> access_allowed: auth access to "uid=vp,ou=People,dc=teraphim,dc=de" 
"userPassword" requested
=> slap_access_allowed: backend default auth access granted to 
"uid=vp,ou=People,dc=teraphim,dc=de"
=> access_allowed: auth access granted by read(=rscxd)
=> access_allowed: backend default write access denied to 
"uid=vp,ou=People,dc=teraphim,dc=de"


That seems to me that the user does not have the right to right access the 
password. My slapd.conf includes

access to attrs=userPassword
    by self write
    by anonymous auth
    by dn.base="cn=Manager,dc=teraphim,dc=de" write
    by * none

Any ideas?

Cheers
