Full_Name: Antoine TRAN Version: openldap-servers-2.4.44-21.el7_6.x86_64 OS: CentOS Linux release 7.7.1908 (Core) URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (213.190.88.94)

I use slappasswd to generate SSHA password. The issue is it behavior is different whether I submit the password - in stdin or in command-line '-s' - and from a secret file '-T'. Command: slappasswd -h {SSHA} => write 'd' twice as password slappasswd -h {SSHA} -s d

provides working SSHA.

But: echo d >/run/secrets/rootpw slappasswd -h {SSHA} -T /run/secrets/rootpw provides a valid SSHA, but that does not match the password.

My multiple test are done by replacing rootpw in /etc/openldap/slapd.conf, regenerating with: systemctl stop slapd sed -i -e "s,rootpw .*$,rootpw ${ROOTPW_HASH},g" /etc/openldap/slapd.conf slapcat -n 0 -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d systemctl start slapd ldapsearch -D "${ROOTDN}" -w "${ROOTPW}"

The content of the secret file can be "d" or "d\n", it does not make a difference. Also, if I change the schema from SSHA to just a fixed salt, the '-T' seems to work as expected: (a) slappasswd -c 123 => write d twice (b) slappasswd -c 123 -s 123 (c) slappasswd -c 123 -T /run/secrets/rootpw

(a), (b) and (c) gives the exact same hash. But I cannot put a fixed salt and use SSHA, slappasswd prevents me from that, with an error schema already provided.

I saw the same issue in another openldap mail: https://www.openldap.org/lists/openldap-software/200805/msg00060.html but no answer.
