must pam-related error becase can browse ldap-database "ldapsearch -x uid=<username>". goes wrong ....but cant figure out is
or suggestions on topic appreciated, because im stuck this...

pam common-auth (should ok), common-password , common-session looks this:

## common-auth ##
###############
# here per-package modules (the "primary" block)
auth [success=2 default=ignore] pam_unix.so nullok_secure
auth [success=1 default=ignore] pam_ldap.so use_first_pass
# here's fallback if no module succeeds
auth requisite pam_deny.so
# prime stack positive return value if there isn't 1 already;/
# avoids returning error because nothing sets success code
# since modules above each jump around
auth required pam_permit.so
# , here more per-package modules (the "additional" block)
# end of pam-auth-update config
