Ansible免密登陆权限问题

Question

今天安装了ansible
执行了
sh-keygen
ssh-copy-id -i .ssh/id_rsa.pub username@ip

        管理机执行出现以下情况：
        [weblogic@yhb128 ~]$  ansible 192.168.232.145 -m shell -a  'pwd' -u weblogic

[DEPRECATION WARNING]: ACCELERATE_PORT option, Removing accelerate as a connection method, settings not needed either. . This feature will be removed in version 2.5. Deprecation warnings
can be disabled by setting deprecation_warnings=False in ansible.cfg.
192.168.232.145 | SUCCESS | rc=0 >>
/home/weblogic

[weblogic@yhb128 ~]$ ansible 192.168.232.145 -m shell -a 'pwd' -u web1
[DEPRECATION WARNING]: ACCELERATE_PORT option, Removing accelerate as a connection method, settings not needed either. . This feature will be removed in version 2.5. Deprecation warnings
can be disabled by setting deprecation_warnings=False in ansible.cfg.
192.168.232.145 | UNREACHABLE! => {
"changed": false,
"msg": "Failed to connect to the host via ssh: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).\r\n",
"unreachable": true
}

受管理机用户情况：
[web1@yhbnew ~]$ more /etc/passwd
root:x:0:0:root:/root:/bin/bash
bin:x:1:1:bin:/bin:/sbin/nologin
daemon:x:2:2:daemon:/sbin:/sbin/nologin

sshd:x:74:74:Privilege-separated SSH:/var/empty/sshd:/sbin/nologin
weblogic:x:500:500::/home/weblogic:/bin/bash
web1:x:501:501::/web1:/bin/bash
web2:x:502:502::/home/web2:/bin/bash

用户目录为/home下的可以被ssh免密登陆，而web1用户目录为/web1，却不可以被免密登陆，这是为什么？
经确认weblogic与web用户的用户目录下都有.ssh/authorized_keys
